Different Types of Stair Tread Steel Grating
1. The stair tread steel grating produced by our company is divided into four types according to the no front guard plate and the connection with the ladder beam, namely T1, T2, T3, T4.
![]() | ![]() |
T1 Series:Welding fixed, no front guard plate | T2 Series: Bolt fixing, no front guard plate |
![]() | ![]() |
T3 Series: Welding fixed, front guard plate with pattern | T4 Series: Bolt fixed, front guard plate with pattern |
T1 Series Stair Tread Steel Grating: The fixed stair tread is welded directly on the ladder beam without adding the side board of the tread. It is relatively economical and durable but not easy to disassemble. The bolted grating step needs thicker side boards on both sides, and holes are drilled on the side board. The installation is directly fixed by bolts, which can be recycled and reused. Customers can customize according to their actual needs, and can be made into various sizes with appropriate types of steel gratings to match the corresponding stairs.
T2 Series Stair Tread Steel Grating: T2 type stair tread is also one of the most commonly used grating steps. It is easy to disassemble and assemble, and can be used many times. The bolt fixation does not damage the galvanized layer on the surface of the steel grating board. The shape is similar to the T1 stair tread, and the price is slightly more expensive than the T1 model stair tread.
T3 Series Stair Tread Steel Grating: Compared with the T1 steel stair treads, the T3 steel stair treads has a patterned angle steel anti-skid strip on the outermost side, which makes the overall effect of the step board more beautiful after the installation is completed. The price is slightly more expensive than the T1 type grating step. The installation method can still be installed by welding, which is firm and stable. The welding and fixing can make the steel grating stronger, and can also reduce the probability of theft of the step board and play a certain role in preventing theft. The surface is more beautiful than T1 type stair treads, and is often used in places with higher requirements for foreign companies, schools, and exhibitions.
T4 Series Stair Tread Steel Grating: T4 steel stair treads integrates the advantages of T2 and T3. The side plates are reinforced with thickness, the middle is punched, and the outside is welded with patterned angle steel. It can be bolted and is relatively beautiful. It is the most expensive step board among the four types. Some types of step board steel grille are easy to disassemble and assemble and can be used many times.
2. According to the different types of surface, stair tread steel grating can be divided into smooth stair tread and serrated stair tread.
