It is made of stainless steel, which has good wear resistance and durability, and will not rust and fall off easily even if used for a long time. Stainless steel door handles can be found on all types of doors including exterior doors of residential and commercial buildings, internal doors, cupboard doors and vehicle doors.

Types of Stainless Steel Door Handle

Door Lever Handle
Door lever handles are the most popular type of door handle and are commonly used in both residential and commercial settings. These handles are easy to operate and can be used with just one hand, making them a convenient option for high-traffic areas. Door lever handles come in a variety of styles and finishes, making them a versatile choice for any type of door.

Pull Handle

These handles are round and require twisting to operate, making them a good option for doors that do not require frequent access. Knob handles come in a variety of styles and finishes, making them a classic and versatile option for any type of door.

Benefits of Stainless Steel Door Handle

Corrosion Resistance
Stainless steel door handles for external doors, exposed to longer contact with water and moist air, don't rust if they have an adequate material and are occasionally maintained.
For faster manufacturing times and simple production many manufacturers use combination of different non-ferrous materials, such as aluminium and brass. Non-ferrous metals in door handle oxidize in the air and transmit it to other nearby parts, which results in corrosion. That's why it's important to produce even screw thread, thread pin, mount, tube and other essential parts for a door handle from stainless steel. Properly processed stainless steel door handles are corrosion free and don't rust. In fact, even in moist and salty environment they don't rust, but need to have better, more resistant stainless steel.

Aesthetic Appeal
Whereas, for example, a brass door handle that has been lacquered may fade or start to change colour over time, stainless steel door handle preserves its appearance. If properly surface treated, stainless steel door handles have exquisite shape and noble look, while carefully grinded surfaces and edges significantly contribute to product perfection.
The supernatural shine of stainless steel is more than obvious to the human eye, as it is one of the most commonly used materials in domestic and social environments. Silver perfection seems to be constantly fashionable, and it's easy to complement it with other accessories on the doors, such as stainless steel rosettes, hooks, locks, house numbers or the decorative elements of a modern home portal.

Long-Lasting Durability
Stainless steel as an extremely strong metal maintains structural stability and is more shockproof to surfaces. Stainless steel gives door handles have practically infinite life span. Durability and its long-lasting lifetime often make a door handle "the icing on your door".

Minimal Maintenance
While other materials require special maintenance and care when choosing cleaners, stainless steel door handles for external doors keep exceptional visual appeal and are easy to clean.
The use of soap, water or mild detergent is best recommended when cleaning stainless steel door handles. You can also use other cleaners, but they should not contain aggressive and abrasive ingredients. The use of chlorine cleaners, such as bleach, cleaning powders and various oven cleaners is not recommended.
The stainless steel door handles can be best cleaned with the soft side of a cleaning sponge or cloth, but certainly not with steel wool or metallic scourers. Regardless of the fact that stainless steel door handles require minimal maintenance, it's still recommended to clean them at least once per month.

Hygienic Surface
One of the reasons stainless steel door handles are hygienic is because the material generally doesn't have pores. Bacteria with dirt rarely survive, while door handles are easily disinfected. Due to this benefit, stainless steel door handles are usually used on doors in sanitary and hygiene conditions. Even surgical tools and medical equipment are usually made of it, because of its ability to be sterilized and durable. Properly mirror polished stainless steel door handles are even more hygienic and can be successfully persistent in though environments.

Recyclable Material
In days of environmental issues stainless steel can emerge as an excellent recyclable material. It is 100 % recyclable and that 60 % of new stainless steel comes from an old one that has already been recycled. The purchase of stainless steel door handles, therefore, helps to protect the environment and reduces waste.

Factors To Consider When Choosing a Stainless Steel Door Handle

Design Style
Consider the design style theme you desire for both the external and internal look of your door handles.

Security Factors
For your front door, evaluate whether you require additional locking security, such as double deadbolts or Smart Locks, with your pull handles or lever door handles.

Door Size and Compatibility
Take into account the size of your door, ensuring that the stainless steel door handle is proportionate and not overly large. Also, consider handles that will fit the door, especially if you have a screen door in front. Pay attention to the handle's projection to prevent it from protruding too far out.

Room Functionality
Consider the room to which the door leads, whether it's a wardrobe, laundry room, toilet, bathroom, bedroom, or any other space.

Required Function
Determine the function you need for your stainless steel door handle, such as a dummy set, passage set, privacy set, or keyed set.

Complementary Finishes
Select a finish that complements your surroundings, such as black, satin gold, white, satin nickel, or stainless steel. Some pull handles can be powder coated, and roses on lever door handles can also be customised. If desired, you can coordinate your door hardware with your cabinet hardware or fixtures.

Additional Accessories
Enhance the overall look by adding door accessories like door stops, flush bolts, cabin hooks, or hinges.

Installation Considerations
Decide whether you will install the door handles and accessories yourself or hire a professional installer. Rest assured that all our door handles come with instructions.

User-Friendliness
Take into account the comfort, practicality, and function of the door handles, especially if they will be used by the elderly or children.

FAQ

Q: How to clean a stainless steel door handle?

A: Prepare a cleaning solution by combining filtered clean water and a small amount of liquid detergent in a bucket. Use a cleaning sponge for the next steps.
Dampen the cleaning sponge with the soapy water solution.
Gently wipe and clean your handles with the damp sponge, ensuring to cover all areas.
After cleaning, use a soft cloth to wipe off any excess moisture and thoroughly dry the handles.
If your stainless-steel handles have tea staining or stubborn stains, use a mild abrasive cleaner and scrub gently to loosen the grime and remove the discoloration. Avoid using steel wool as it can leave residue and promote rusting.
Always clean and rub the stainless-steel handles in the same direction as the grain to avoid damaging the finish and causing surface crevices that may lead to corrosion spots. This is especially important for polished stainless steel handles.
Once you have used a cleaner, polish the handles with a soft microfiber cloth to restore their shine and maintain their quality. Regular care and maintenance will ensure long-lasting use.

Q: How is it possible for a stainless steel door handle to start corroding?

A: Low Quality Stainless Steel
The quality of the door handle begins with the choice of high quality material, procured from the best certified European manufacturers.
Even if the material looks good when new, its lack of quality will show after the application of surface treatment.
During grinding, small pores can arise, which are the side effects of casting. If the manufacturer is not trained to notice such blemishes, the door handle will begin to corrode.
Non-Ferrous Metals In The Door Handle
Many manufacturers create a stainless steel tube and fill it up with non-ferrous metals (aluminium, bronze, brass, etc.), which can quickly lead to corrosion. These procedures are used for: faster manufacturing, simpler processes and lowering prices by using cheaper metals.
However, they overlook the electrochemical interaction of different metals, which creates a galvanic cell, leading to the corrosion of coloured metals when exposed to the air. Rust then moves to nearby parts (i.e. corrosion of the aluminium door panel), which then travels to the surface.
This is why it is important that screws, mounts, tubes and other key materials of the door handle are made of stainless steel.
Inappropriate Surface Treatment
Correct surface treatment is the most important factor in preventing corrosion.
Long-term experience in grinding offers manufacturers the necessary insight to identifying the best anti-corrosion grinding method. If the manufacturer is in a rush or does not pay special attention to this, the door handle will soon start to corrode.
Polished door handles are definitely more resistant to corrosion than satinised door handles.
Satinised door handles can also offer the highest protection against corrosion if taken care of properly.
Correct polishing diminishes the small pores that can result from surface treatments. This improves corrosion resistance and reduces the absorbency of microscopic elements.
This is also one of the reasons why such treatment is used in the nautical industry, where the conditions for the durability of metals are very demanding.
Wrong Choice Of Stainless Steel Type
If the house is not near a coast, main road or other aggressive environments, then a standard 304 stainless steel (A2 4301/1.4305) is sufficient.
Problems may occur when a door handle of the same stainless steel type is mounted near the sea or in an area where salty air is prominent.
For such environments, 316 stainless steel (A4 1.4404) is more appropriate, since it has a greater anti-corrosion protection. If the door handle is polished and properly maintained, corrosion will not occur.
Improper Cleaning And Poor Maintenance
Incorrect cleaning and poor maintenance are the most common reasons for rapid corrosion.
Stainless steel may be very resistant, but it should not be cleaned with abrasive solutions, such as cleaners for glass, ovens, silver, brass, cement stains, or soap concentrates, chlorine cleaners or solutions with hydrochloric acid, etc.
The use of rough brushes with strong bristles, steel wool used for cleaning stubborn stains from dishes, the rough side of a cleaning sponge made of iron or steel fibres is also forbidden.

Q: What are the common shapes and styles of door handle?

A: Oval
Door handles will be more tubular with no defined edge and accompanied by curved edge back plates. Door knobs will be oval, and often smooth and polished.
Round
This style of door handle will generally be smooth and circular, while door knobs will be perfectly round in shape. They will be placed in front of a round backplate.
Angular
Door handles may have square or rectangular backplates, with the handle itself also being rectangular with crisp edges.
Classic
Traditional Victorian style may see a large rectangular backplate accompanying a decorative curved handle. This will usually be in brass.
Contemporary
Modern and contemporary style handles are often sleek, simple and minimalist. They will often be in chrome or a statement colour, like bronze or black, with little or no backplate.

Q: How to tighten door handles?

A: Should your door handle be loose, thankfully it's almost always an easy fix. For an interior door with unexposed screws:
Use an Allen key to loosen the set screw on the side and remove the handle.
Next, use a flat head screwdriver and remove the cover plate; this will expose two Phillips screws.
Tighten the screws on each side with a Phillips screwdriver to secure the handle.
Put the door handle back together by placing the cover plate back on, inserting the handle and tightening the screw set with the Allen key.
For an interior door with exposed screws, you simply need to tighten the screws either side of the handle with a Phillips screwdriver.

Q: Are stainless steel door handles reversible?

A: Generally speaking, door handles are reversible. You're able to remove the door lever, rotate the handle and install it on the other side of the door, all while ensuring that the latch mechanism operates exactly the same. Here's how:
Loosen the level by rotating the screws which hold the lever in place, you should then remove the section of the latch that sticks out of the edge of the door.
Remove the various lever pieces from the door, rotate the lever setup and hold it against the door so that the setup is upside down and back to front. Check that the lever fits with any existing holes, drilling or enlarging where necessary to fit with your adjustments.
Set the internal latch within the door frame, sliding the edge latch piece back into place.
Reinstall the lever pieces and any external sections of door hardware that you removed earlier and test that the door opens and closes smoothly.

Q: What is the difference between the 201, 304 and 316 grades of stainless steel handles?

A: As the grade increases so does the resistance to external weathering and corrosion. 316 stainless steel is the best grade of stainless steel to use if you live next to the coast whereas if you live inland you may be fine with lighter grades. As a general rule-of-thumb, when it comes to exterior stainless steel door handles, the 201 stainless is resistant in mild to moderately corrosive environments, 304 has a high resistance to rust and 316 is a marine stainless steel.

Q: What are different types of lever door handles?

A: Lever Latch Door Handle
lever latch door handle is one of the simplest lever door handles. A simple latch keeps this type of door closed. The user can use the lever handle (hence the name) to release the latch and open the door.
The door lever latch usually has an elongated handle, and pushing the handle down can operate the internal latch mechanism. Some door handles work based on this mechanism. Turning the door handle will have the same effect.
This lever latch handle is usually used in homes or offices. Due to the lever latch mechanism, there is typically no lock. This makes this type of door handle very suitable for interiors that do not require a locking mechanism. External locks can be installed.
Bolts and chain locks are usually installed together with lever locks to provide more privacy.
Keyed Lever Door Handles
The keyed lever door handle has a locking and key mechanism on both sides to ensure safety.
The keyed entry door levers are used to enter the front door, patio door, garage door, or other exterior doors for some rooms with higher privacy of your home.
Some have a button inside. You can press this button to lock the door.
When you turn the internal lever, the button is unlocked. Other keyed entry lever handles have a twist mechanism on one side, which you can turn to lock or unlock the door.
The main feature of a lever door handle with a key lock is that it has a key lock cylinder outside the door, which can also be locked with a key.
Simultaneously, you can use the button on the inside of the door or turn the button to close or open the door.
Passage Lever Door Handles
Passage lever door handles are similar to virtual door handles. They are not locked but are used to open doors and move between rooms.
Passage door levers are very suitable for hall doors, indoor corridors, closets, and other spaces that do not need to be locked but still require a valid door pole on the door. They are also called keyless entry door lever.
Sometimes, the channel joystick is used on the outer door, and a lock pin is installed on it.
In these cases, a simple locking mechanism that does not require a key but still provides privacy is advantageous.
Privacy Lever Door Handle
The twist-lock or button lock of the privacy lever door handle can only be used from one side. It is also called the one-sided door lever.
Some privacy door lever handles with push-button locks have a pinhole on the outer knob and a universal key to open the lock.
These door handles are usually used in bathrooms, bedrooms, and other rooms that require privacy but do not need a key lock.
These privacy lever locking door handle can indicate that the room is occupied, and they can be easily locked from the inside, thus providing security and privacy.
However, it can be unlocked from the outside with an item that fits the knob or handles slot.
These objects (such as coins) can be turned to activate the handle's mechanism and open the door. This is useful if you have children who can lock themselves but need help.

Q: What should you consider when choosing a front door handle?

A: Generally speaking, there are not a huge number of options when it comes to front door handles as any doorknob, door handle on a backplate or on a rose will work perfectly well on any external door. There are some practical benefits to each but, ultimately, the choice should be based on security, aesthetic and functionality.
Aesthetics
In terms of aesthetics, you should usually match your door handle with the style of your home and the door. So, if you live in a more modern, new build home, an antique-looking door handle may not work so well.
Functionality
Another point to consider when choosing a door handle is it's functionality, or how it will be used. Door knobs offer less grip than a handle, but they may fit the style of your home better. The material used is also something to think about as polished brass does not fare as well outside as polished chrome does.
Security
Finally, the security offered by your door handle should also be considered. Additions such as chamfered backplates can allow for extra security to deter any break-ins, so if you are looking to increase the security of your home, understanding how to choose the right door handle can help.

Q: What are the advantages of using stainless steel for door handle?

A: The door handle made of stainless steel is environmentally friendly and pollution-free, and does not contain formaldehyde.
The advantage of stainless steel door handles is that there are many grades. Made of higher grade stainless steel, the handle has higher corrosion and oxidation resistance.
The Stainless Steel 304 door handles are most commonly installed indoors.
If stainless steel door handles are used in outdoor, seaside properties, swimming pools or ocean engineering, it is generally recommended to use 316 stainless steel door handles because it contains Mo and has good corrosion resistance.
Some models of stainless steel door handles have a fire rating, which means they have been tested and can withstand standard fire conditions for a period of time. This is very important for developers, because this may be a door handle for real estate as required by building codes.
Stainless steel is a non-porous material, which means that dust, dirt and bacteria are difficult to adhere to.
Therefore, stainless steel door handles have the advantage of being easy to keep clean, which makes the environment more hygienic.

Q: How often should you clean the door handle?
