OTi Handset Function SKA3 Instruction

Most electric height adjustable desk frame factories have their own handset types. OTi-furniture also has its own type of handset and function.
This type is called SKA3, key button.
∧ ∨  are to lift up and down.
and 1, 2, 3  are three memory keys, which could, say, save a standing height at 1, save a sitting height at 2, and save an afternoon nap height at 3. It will greatly save time by just pressing one of the memory keys to achieve your wanted height.
The last key is not 5. It is an S. S means set. With this key, you could set up the MAX&MIN height, though we have a 650-1300MM height range. You still could shorten this range. And with the S key, you could set the long sit reminder, safety locker, length unit, and so on.

A lot of handset functions mean the electric height adjustable desk is an intelligent desk.

Why AkzoNobel Powder?

Why is AkzoNobel Powder best for a standing desk?

Nowadays, metal furniture in the market is increasingly used in various industries such as home furnishing, outdoors, teaching, and office. Metal furniture generally has a smooth and hard look. This external feature is mainly determined by the base material of the metal and the coating on the base surface. Because of different application scenarios, we not only require the metal substrate surface coating to be beautiful and hard but also require the coating to have gloss, hardness, impact resistance, corrosion resistance, adhesion, and so on.


As one of the metal furniture,  electric height adjustable desks have a higher requirement in terms of the coating because of the special structure–telescope columns. For years, OTi-furniture has been using AkzoNobel Powder on its adjustable desk frames. And it performs outstanding!


Standing in the middle east of China, Akzo Nobel (China)  homed Shanghai, built its plants in Suzhou city, and focused on the decorative markets, expanding its business rapidly. 


Safety is the top concern for furniture manufacturers. An unhealthy coating could cause Asthma bronchiale, rhinitis, immunity issues, and other potential diseases.

Many manufacturers choose AkzoNobel. So does OTi! According to RoHS  Directive (EU) 2015/86 3 amending Annex II to Directive 2011/65/EU, based on the performed tests on submitted AkzoNobel (China) sample(s), the results of Lead, Mercury, Cadmium, Hexavalent chromium, Polybrominated biphenyls(PBBs), Polybrominated diphenyl ethers (PBDEs) and Phthalates such as bis(2-Ethylhexyl) phthalate (DEHP), Butyl benzyl phthalate(BBP), Dibutyl phthalate (DBP), and Diisobutyl phthalate (DIBP) comply with the limits.

Inspection Report

Provided by one of our German customers, the inspection report shows the adhesion test. The test sample is from the cargo before shipment. As adhesion is one of the important characteristics and also it could be operable for field testers. The result is OK. 

Coating thickness

In terms of the electric height adjustable standing desk or other adjustable desks, the telescope design makes the coating requirement relatively high. It requires high-intensive abrasion resistance. Besides the performance of the powder self, the thickness of the coating is the second factor that mainly affects the abrasion resistance. To some extent, the coating thickness decides durability. According to the industry standard of the standing desk, the coating thickness is 60-80μm. Our factory’s operative standard is 80-100μm.

Rub Process

Of the adjustable standing desk, rub happens when the desk is moving. However, the rub is not as serious as people think so. Some users may think the rub is caused by metal against metal. No! Actually, the fight is the plastic parts against the metal tubes, And the metal tube is armed with AkzoNobel Grinding powder. The powder is hard wearing and the thickness could be 80 μm or more. 

Though the protective layer is strong, ten years later, could it be still strong? How about reducing the rub? This is a paradox. If we remove the plastic parts, the desk could be wobbly. If we tighten the tubes, it will consume the powder much, reduce the motor life span, and leave rub marks(don’t worry. Our desk’s rub marks could be erased by an eraser). Theoretically,  there is a critical value. At this critical value, the rub should be min.  And it could be calculated if the coating thickness and tube thickness are constant. Our tube’s thickness is 2MM and the material is high-quality cold-rolled steel, made by Shanghai Baosteel Company, China’s best steel company. That means there is no error range of the tube’s thickness. And the coating thickness is performed by the precision spray painting machine. Our quality inspectors check every batch of painted parts and record them. When these two-part figures are certain, or controllable, the rest is controlled. This is the key part for an electric height adjustable desk. Of course, professional assembly workers also can feel it. Our assembling workers all have at least 3-year experience. 

Since the rub can not be removed. We could also reduce the rub from the plastic parts. The material of our plastic parts is high-end POM. If you know the traits of POM, you would be surprised at the existence of such a perfect material born for electric height adjustable desk frames. POM is short for Polyoxymethylene (Polyformaldehyde), a good-performance engineering plastic. Its nickname is “capture steel”, “super steel”. POM is similar to metal hardness, strength, and steel, in a wide range of temperature and humidity have a good self-lubrication, good fatigue resistance, and elasticity. In addition, it has a better chemical resistance. It perfectly fits metal furniture.


It is very important for furniture to have a good appearance.


The importance of choosing a healthy, durable, and productive adjustable standing desk is self-evident. Paying attention to the coating is equally important. If you want to be our dealer and want to know more other information about our standing desk frames, you are welcome to contact us.

adjustable desk frame

Super Material

Our SXL01 pro including the feet, brackets and beam, all the metal pieces, are made of cold rolled steel, which means with a 120 kg load capacity, the desk can go up or down freely and smoothly. Moreover the thickness of all the metal pieces is 2MM, making the desk frame more stable and durable.

Swell design

There is a slope processing in the foot, greatly reducing the possibility of bumping the user’s foot. And every foot equipped with two alignment feet which can adjust the leg height when the floor is not very flat. It is extremely important to keep the two leg at the same level otherwise too much height difference could cause the up&down system can not work. Also they can touch the floor gently without scratching it, and make the desk more stable. Details show elegance.

The normal adjust speed is 25mm/s. but users can also set their favorable speed. The Max speed is 40mm/s. It is the top speed among standing desks.

Featured Handset

A featured handset is the essential part of a standing desk. SXL01 pro has a handset with the latest version. App, safety locker, memory keys, gyro anti-collision and Max height& min height set, speed set, USB charge…….


Other subtle designs

adjustable desk beam

Motors can be protected by the metal pieces and horizontal placement makes it more durable.

adjustable desk frame wire hole

There are four wire holes on the beam close to the legs. They are designed for the handset wire going into the beam to connect with the control box.
