25X3 25X5 30X3 Galvanized Steel Stair Treads,Steel Ladder , Metal Step Treads
Description:
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.
Step Ladder:
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.
T1 TYPE
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 .
T2 TYPE
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.
T3 TYPE
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 TYPE
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 TYPE
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 TYPE
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.

Features:
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
products according to customers’ drawing.
- Once receiving customers’ inquiries. Our company promises to provide services within 24 hours.
