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.
