Aluminium Grating

2. Aluminium Grating Specifications

Material grade, condition, surface treatment, and final dimensions depend on the specified product configuration.

3. Grating Structure and Surface Options

Open-Grid Bar Construction

Aluminium bar grating uses bearing bars connected by cross bars to form an open-grid panel.

The spaces between the bars allow air and light to pass through and provide openings for liquid drainage. This structure is suitable for industrial flooring applications where a solid plate would not provide the required open surface.

Plain and Serrated Surfaces

We offer two surface options:

• Plain Surface: Features a regular flat upper profile for applications requiring a flat grating surface.
• Serrated Surface: Features a textured upper profile for applications where additional surface grip is required.

The choice depends on the walking conditions and installation environment.

Bearing Bar and Cross Bar Selection

Bearing bar height, thickness, profile, and spacing determine the main bar arrangement of the panel. Cross bar type, dimensions, spacing, and connection method define the corresponding grid structure.

These details must be considered together with panel dimensions, support locations, and loading conditions. For platform and walkway projects, the required load and support span should be established before finalizing the grating specification.

4. Custom Dimensions and Fabrication

We can consider aluminium grating orders based on standard panel sizes or project-specific drawings.

Specific fabrication requirements can include:

• Panel Cutting: Cutting according to specified installation dimensions.
• Non-Standard Dimensions: Panel lengths and widths outside the listed standard sizes.
• Open Ends and Edge Finishing: Specified panel edge conditions.
• Framing: Frame dimensions and arrangement according to supplied drawings.
• Surface Selection: Plain or serrated surfaces, with anodizing or painting where available.
• Installation Accessories: Grating clips, bolts, and fastening requirements specified for quotation.

For drawing-based orders, send us CAD drawings or reference drawings showing panel dimensions, bearing bar direction, support locations, openings, and edge details. We can use these details to review the required panel arrangement and fabrication scope.

5. Manufacturing and Quality Control

Yantai United Steel Structure Co., Ltd. is a metal grating and steel structure manufacturer based in Yantai, Shandong, China.

Our product range includes aluminium grating, steel grating, trench covers, steel stair treads, and steel ball posts.

Our manufacturing facilities cover CNC machining, laser cutting, automatic welding, and punching. Our overall material scope includes carbon steel, stainless steel grades 304 and 316, and aluminium.

We apply a three-stage quality control process across our manufacturing operations:

• Incoming Material Inspection – Checking materials before production.
• Production Process Inspection – Inspecting products during manufacturing.
• Finished Product Inspection – Checking completed products.

For drawing-based grating orders, we also provide computer-aided design and grating layout design support for panel arrangement and fabrication planning.
