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!
