Grating Lines National Defense

Grating Lines National Defense 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.

Grating Lines National Defense:

  • 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.
  • Aluminum
    Aluminum grating has unexpected strength-to-weight ratio. In addition, it is suitable for harsh environments like wet and corrosive.
  • Stainless steel
    Stainless steel grating is the prior choice for food processing factories which needs high sanitarian requirements.

  • US7588657B2 - Pattern-free method of making line gratings
    In accordance with the invention, substrate-supported linear arrays are formed by the steps of adhering a thin layer of polymer between a pair of substrates and separating the substrates perpendicular to the layer. The polymer layer separates to form substrate-supported polymer gratings on both substrates, each grating having a period proportional to the thickness of the layer.
