  Welded Steel Grating for Stair Treads, Walk Way, Platform and Various Floor

  Welded steel grating is one of the most commonly used steel grating, also called metal open bar grating. Welded steel grating is made of carbon steel or stainless steel. Welded steel grating has anti-slip surface, corrosion resistance, good drainage function, high strength and load capacity. So it is widely used as walkway, stair, fence, shelf, ceiling and floor in many places.
   

  Classification of serrations:

•  S1 Sharp Serration.
•  S2 Interrupted Serration.
•  S3 Trapezoid Serration.
  

  

  

  Features:
  * High strength and load capacity.
  * Anti-slip surface.
  * Corrosion resistance.
  * Good drainage function.
  * Easy to install and maintain.
  
  Specifications:

• Material: carbon steel and stainless steel.
• Surface treatment: galvanized, mill finished, painted, powder coated, etc.
• Surface type: standard plain surface, serrated surface.
• Bearing bar type: plain bearing bar and serrated bearing bar.
• Standard pitch of cross bar: 50 mm & 100 mm.
