Product Description

Stair Tread Steel Grating - High Strength, Safety, Fireproof

Stair tread steel gratings, also called grating steps, are made of low carbon steel or stainless steel. It is one of the most widely used and popular types of steel gratings. With the features of high strength, high bearing capacity, wear resistance, resistance to extreme temperature wind and rain, non-slip, anti-corrosion, beautiful and easy to install and remove extend the lifespan, stair tread steel grating is widely used as different types of steel ladders in the factory, school, park, stadium, civil and commercial buildings.

Different classifications of stair tread steel grating

• According to the different production methods, straight stair tread steel grating can be divided into welded stair tread, press-locked stair tread, swage-locked stair tread and riveted stair tread.
• Welded stair tread is the most widely used type in most industrial and commercial applications, it is easy to install.
• Press-locked stair tread and swage-locked stair tread can provide higher strength, and when the surface type is serrated surface, it is more safety.
• 
• According to the different types of surface, straight stair tread steel grating can be divided into smooth stair tread and serrated stair tread
• 
• According to the different installation method, straight stair tread steel grating can be divided into welding connections stair tread and bolts connections stair tread.
• Welding connections stair tread: It is directly welded to the bearing bar, do not need to add end bar, compared with bolts connections stair tread, it is more economical and durable but not easy to dismantle.
• Bolts connections stair tread: On both sides of the stair tread need to end bar, poke on the end bar and fix it by bolts, it can be reused.
• Customers can be customized according to their actual needs, the appropriate type of steel grating made into a variety of sizes.
• According to the different front nosing, straight stair tread steel grating can be divided into without nosing, checker plate nosing, vertical stripped plate nosing, round hole plate nosing and abrasive nosing.
