Product Description

Product Description

Hot Dipped Galvanized Light / Medium / Heavy Duty Steel Grating

Galvanized Grating  has been main candidate for industrial floor market whether for the plant flooring or equipment flooring. With high strength-to-weight ratio and recyclability, bar gratings can meet almost any configuration. Compared with solid metal plates or other plates, open area makes bar grating need less or no maintenance. In addition, opening area allows for pass of small debris like leaves.

Treatment Finish:

Standard Gratings that are hot dip galvanized are also available. Galvanizing Gratings makes them ideal for use in corrosive environments. It protects the gratings from rust and prevents corrosive substances from coming into contact with the steel. Gratings are also provided in Self color or painted.

All the products come from our factory are strictly in compliance to ISO standards. We've been ISO 9001 accredited since 2002!

Product Parameters

 

Material:

• Mild carbon steel
  Steel grating is the most popular choice for many grating applications. It is often hot-dip galvanized or PVC coated to extend service life.

• Stainless steel
  Stainless steel grating is the prior choice for food processing factories which needs high sanitarian requirements.

Configuration:

Our typical panel configuration has bearing bars with perpendicular cross bars and  flat bar around the edge of the panel to create additional strength during loads.
