Pressure Lock Grating – Unique Combination of Uniformity and Precision

This is a press lock grating with smooth surface.

Various pressed gratings provide multiple choices for your different applications, and serrated surface is slid resistant for safety.

Press lock grating is also called pressed grating or pressure lock grating, which is made of low carbon steel, stainless steel or aluminum. The press-locked grating is constructed with two close-tolerance slotted bars bonded together by tremendous hydraulic pressure. And this production can let press-locked grating be a permanent locking. With high strength and firm structure, it's widely used in industrial factories or parks, commercial buildings, municipal engineering as stair treads, platforms, walkways, security screens, tree covers, trench covers, drainage covers and so on. Serrated surface is also available for anti-slide effect.

Feature

Specification

  • Material
    Low carbon steel, stainless steel and aluminum.
  • Surface treatment
    Galvanized, painted and powder coated.
  • Surface type
    Standard plain surface, serrated surface.
  • Cross bar spacing
    2" or 4".
  • Bearing bar spacing
    Standard is 15/16" or 1-3/16".
  • Classification
    • Full-locked steel bar grating
      The bearing bars and cross bars are notched and have the same height.
    • Heavy-duty pressed bar grating
      The bearing bars are higher than the cross bars and they are all notched.
    • Press-locked bar grating
      Only the bearing bars are notched, the cross bars are common plain steel. And they have different height.
    • Louver bar grating
      The notches of bearing bars are at a angle of 30° or 45°. The cross bars insert into the bearing bars before being pressed.
