1.5mm Hot Dipped Galvanized Checker Plate Nosing Stair Treads And Walkway

1.5mm Hot Dipped Galvanized Stair Treads And Platform Walkway

Steel bar grating with high strength and firm structure is made up of carbon steel, aluminum steel or stainless steel. According to the

manufacturing methods, it can be divided into four types: welded, press-locked, swage-locked and riveted gratings. According to the surface shapes, it can be divided into smooth and serrated gratings. With various styles and sizes for choice, steel gratings are widely used in everyday life, such as stair treads, walkways, platforms, floors, various covers, wheeled equipment, security screens, heavy duty constructions and so on.

Due to the extremely strong and durable for all the bearing application,bar grate stair treads has become the most popular grating in the markets.The stability makes them have a much higher performance in the application.

Different classifications of stair tread steel grating

Stair treads are divided into four models due to whether the front checkered plate and the mode of connection with ladder beam,

labeled T1, T2, T3, T4, T5, T6.

T1: Welding fixing stair tread without front plate.

T2: Bolt fastening stair tread without front.

T3: Welding fixing stair tread with front checkered plate.

T4: Bolt fastening stair tread with front checkered plate.

T5: Welding fixing stair tread without front Anti-slip strip.

T6: Bolt fastening stair tread with front Anti-slip strip.
