Product Description

Galvanized grating, also called galvanized steel grating or galvanized steel bar grating, refers to the steel bar grating made of mild carbon steel through hot dipped galvanized surface treatment.


Gratings over drains and air vents are used as filters, to block movement of large solids (e.g. people) and to allow movement of liquids. A register is a type of grating used in heating, ventilation, and air conditioning, which transmits air, while stopping solid objects

Galvanized steel grating with heavy zinc coating protection serves widely as strong, quick and durable bearing structural elements in offshore oil rig platforms, refineries, walkways, and many other industries. Steel gratings galvanized make an better choice over non-galvanized steel bar grating due to the fact that the galvanized coating helps protects the steel from corrosion.

Galvanized Gratings for oil operation platforms are mostly made of heavy welded type steel bar grating heavily galvanised. Steel gratings serrated combined with diamond pattern checker plate are safer and popular stair tread and flooring material for offshore oil platform constructions.

Aluminum grating bar is lightweight, corrosion resistant, and fully recyclable. With an unmatched strength-to-weight ratio, these products are ideal for both industrial and architectural applications. Manufactured from ASTM B221, 6063 or 6061 alloy or other steel materials.
, also known as Swagged Aluminum Bar Grate is light weight, yet strong and durable for all load bearing applications that need high corrosion resistance. Aluminum Brating is available in a variety of bearing bar spacing, thicknesses and heights depending on applications and load requirements. Available in either smooth top or serrated for added slip resistance.
How to produce aluminum grating?
Arrange a plurality of punched aluminum strips ( load bar) at a certain distance, insert the aluminum square rod ( Cross Rod) into the arrranged load bar holes, press the part of the cross rod between the load bars to expand, tighten and fix the load bars, and form a grating plate together with the cross rods.
The load bar can be rectangular, I-shaped and T-shaped. 6061 and 6063- T6 aluminum alloy is the most commonly used materials for aluminum grating.

Aluminum grating is an ideal choice when corrosion-resistant, lightweight materials that do not affect its load capacity and mechanical strength is required. Made of ASTM B221, 6063 or 6061 alloy, aluminum grating has great versatile and durable and is mainly used for platform ceilings and outdoor curtain walls.
Aluminum bar grating is lighter than steel grating and has high load carrying capacity.
Aluminum gratings are made of aluminum alloy featured by cheap, economical and practical.
Smooth and serrated surfaces are available. Good anti-slip performance for safety protection.
Excellent corrosion and rust resistance for durability.
A variety of specifications and styles are available to meet various application environments.
Cross bars are fully locked within the bearing bars, slightly below the top surface. It has clean and crisp lines. With nearly 80% open area, it is commonly used in public areas and is the industry accepted standard for industrial applications. If anti-slip is required, swaged rectangular aluminum gratings with a serrated surface are available upon request.
Cross bars are permanently locked within the bearing bars to lock the pressure via unique extruded cross bars. Swaged flush-top aluminum grating provides an enhanced walking surface for areas subject to continuous pedestrian traffic. If anti-slip is required, we can provide swaged flush-top aluminum gratings with a serrated surface. It is mainly used for public areas.
Specification
Bearing bar size: 1″ x 1/8″ to 2-1/2″ x 3/16″ with 1/4″ increments;
Bearing bar spacing (center-to-center): 1-3/16″, 15/16″, 11/16″ and 7/16″;
Cross bar spacing (center-to-center): 4″ or 2″.
Supported by I-shaped extruded bearing bars, swaged I-bar aluminum grating carries the same load as the swaged rectangular aluminum grating with lighter weight and less costs. In addition, the striations at the top and bottom surfaces of the I bar increase the friction and provide high slip resistance performance.
Specification
Bearing bar size: 1″ x 1/4″ to 2-1/2″ x 1/4″ with 1/4″ increments;
Bearing bar spacing (center-to-center): 1-3/16″, 15/16″, 11/16″ and 7/16″;
cross bar spacing (center-to-center): 4″or 2″.
