Press Locked Grating Constructed By Hydraulic Pressure

Press-locked Grating - Constructed by Hydraulic Pressure

Press-locked grating is also called pressure locked grating or press-locked steel bar grating. Basically, the press-locked grating have the same load capacity with the welded steel bar grating. The difference between press-locked grating and welded steel bar grating are joint connection technology and cross bars.

Cross bars of welded steel bar grating are twisted square rods and the bearing bars are rectangular bars or I type bars. Both the bearing bars and cross bars of press-locked grating are rectangular bars.

Compared to welded steel bar grating, which is produced through resistance-welding process, the press-locked grating is constructed with the two close-tolerance slotted bars bonded together by tremendous hydraulic pressure. This production can let press-locked grating be a permanent locking.

Press-locked grating and swage-locked grating has excellent lateral stiffness, which can be used in some special applications. And the serrated surface is available for press-locked grating.

Specifications

• Material: low carbon steel, stainless steel and aluminum.
• Surface treatment: galvanized, painted and powder coated.
• Cross bar spacing: 4" or 2".
• Bearing bar spacing: standard is 1-3/16" and 15/16".

Features

• Smooth surface.
• Good air, light and water circulation.
• Firm and durable.
• Temporary or permanent applications.
• Stainless steel press-locked grating for alkali and acid resistance.
• Aluminum press-locked grating for light weight and corrosion resistance.
• Painted or galvanized surface treatment for longer service life.
• Excellent lateral stiffness.
• Serrated surface for anti-skid performance.
• Press-locked grating can be used combined with checker plate for further skip resistance.

Applications

• Press-locked grating has the similar application with welded steel bar grating and swage-locked grating.
• Press-locked grating can be used as stair treads, platforms, walkways in industrial factories or parks.
• Press-locked grating can be used as security screen in the commercial buildings.
• Press-locked grating is widely used in the municipal engineering as tree cover, trench cover and drainage cover.
