25X3 25X5 30X3 Galvanized Steel Stair Treads,Steel Ladder , Metal Step Treads
Stair treads in each of these metal grating types come in both plain and serrated styles. Our serrated stair treads, also known as safety treads, are specifically designed to offer good protection against slips in areas prone to oil or other hazardous elements. Therefore, metal safety treads are perfect for industrial facilities or outdoor sites where slippery conditions may exist from time to time.
In addition to producing stair tread, we also can make the stair tread into steel ladder. In order to reduce the workload of the construction site, reduce the cost. Our steel ladder can be whole hot dip galvanized after finished, avoid the later welding construction destroy the galvanized layer. Please refer to the specifications of the selection of steel ladder atlas, also can inform our the height of the required, slope, we also can according to your special needs to processing customized specific steel ladder.
We manufacture different styles of stair ladders that used in family,industry and construction.
Material: mill steel black and hot dip Galvanizing / and stainless grating
Usage: ladder, flooring walkway, platform ,steel structures, stair tread, well cover, trench cover, sump cover,compound gratings, storage shelves,fences and handrail so on for construction project, oil project, seaport, power plant, water plant, defense project, chemical factory and so on.
Stair treads is a kind of useage of steel grating, usually we have two methods to fasten the stair treads: by welding or clamps. Thus according to different fixing methods, the stair treads is classified to 6 types. (See the pic below for reference)And among them, T1 and T4 are most popular one.
Stair Treads using common, ordinary steel flat bar to make and close ended system, not welding pattern guard board and antislipstrip, not welding installed side plate and checkered plate, its simple structure. When using it, we only need to weld it on the steel beam, it is very simple,economic and practical, and such stair tread is widely used in the smaller project .
Using common steel welding production, both ends of the stair tread are banded with side plates, On each plate, there is 14 mm in diameter round hole and a long round hole. The side plate chamfering for easy installation. Production is completed need to punch on the steel beam then with bolt to install. This type is used more widely, features: removable and use again.
This type of stair treads is the most widely used. The front end welding pattern plate protect nosing, and plays the beautiful, prevent slippery, wear resistance role. When installation, the way by welding installation, simple and saving time. With the checkered plate covering the sharp edges and corners, avoid the slippery to knock against caused serious damage.
T4 stair tread owns the T2 bolt installation advantages and T3 beautiful safe advantages. Since it can be with bolts installation, facilitate disassembling ; The decorative pattern and welding plate protect nosing, beautify and security two not mistake. Reuse efficiency is high, set the advantages of the above several types, so the price in the series is also the highest.
T5 stair tread is using belt ditch shape steel make protect nosing instead of decorative pattern plate. The effect, the quality, usage and method of use are same as T3 type .This type is used less.
T6 Stair tread also use belt ditch shape steel do protect nosing instead of decorative pattern plate . The effect, the quality, usage are the same as T4 Type. Due to apparence of the bar steel nosing not nicer than decorative pattern plate , so this Type is also used less.

Saving material: the province of the material to withstand the same load conditions, and accordingly, can reduce the material of the support structure.
Reduce investment: saving materials, Province the artificial, Province duration, free cleaning and maintenance.
Construction is simple: in the pre-installed support on national folder with bolt or welding to complete one.
Save Duration: No on-site reprocessing, installation is very quick.
Durable: the factory by the hot-dip zinc treated with preservatives, impact resistance and stress ability.
Modern style: beautiful appearance, design specifications, air and light, giving a sleek, contemporary feel to the whole.
Light structure: the timber is small, light and easy lifting.
Anti-plot dirt: the plot is not the rain, snow and dust.
Reduce wind resistance: good ventilation, the case of wind drag, reducing wind damage.
The design is simple: No small beam, simple structure, designed to simplify; without detail design of steel grating, can only
- We can provide free steel bar grating samples of small sizes, but customers need to pay the express cost.(This can be discussed)
- OEM is accepted. We have technical engineers. Then we can design steel bar grating for customers’
projects, and make
