China Plane Ruled Grating Manufacturer
A planar scribed grating is a dispersive element that uses a diamond tool to mechanically scribe parallel grooves on a precision substrate. By controlling the blaze angle of the scribed grooves, diffraction energy can be concentrated to specific orders and wavelengths.
Key Advantages
• Blaze Characteristics: Diffraction efficiency up to 90% or more
• Wide Range of Line Densities: 80 lines/mm - 3600 lines/mm
• Customizable Groove Shape: Blaze angle can be optimized according to laser wavelength
Typical Applications
Laser tuning, fluorescence spectroscopy, ICP-OES emission spectroscopy

Plain Steel Bar Grating is a heavy-duty structural flooring configuration that utilizes flat bearing bars as primary load-carrying members. Connected with cross bars, it forms an open grid structure widely utilized across industrial walkways, platforms, stair treads, drainage covers, and access areas.
Selecting the right specification depends heavily on structural parameters such as clear span, design load, bearing bar dimensions, and surface treatment, rather than relying solely on standard panel sizes.
Primary Applications in Industrial Engineering
Plain steel bar grating provides a reliable, open-surface flooring solution that maintains structural integrity while allowing fluids and light to pass through.
Industrial Walkways
Ideal for elevated pathways, maintenance routes, and service platforms in processing plants. The open grid prevents liquid accumulation.
01
Maintenance Platforms
Built around heavy machinery, pumps, tanks, and motors. Dimensions must align with support structural layouts.
02
Steel Structure Mezzanines
Integrated into pipe racks, equipment support structures, and multi-level industrial framing.
03
Stair Treads
Fabricated to exact dimensions with designated bearing bar orientations and secure fixing provisions.
04
Drainage & Trench Covers
Frequently deployed over drainage channels and service trenches where pedestrian and light vehicle access is required.
05
To ensure structural safety and compliance, procurement teams should evaluate the following parameters before ordering:
Confirm the Span: Determine the clear distance between supporting members. Bearing bars must run parallel to the primary span direction to transfer loads effectively.
Specify Bearing Bar Dimensions: The depth, thickness, and spacing of the bearing bars determine the overall load capacity and allowable deflection.
Define Cross Bar Arrangement: Cross bars maintain grid stability and transverse rigidity, impacting opening sizes and foot traffic comfort.
Evaluate Design Loads: Account for uniform loads, concentrated loads, pedestrian traffic, and potential wheeled/trolley traffic.

Material & Surface Treatment
Carbon Steel
Cost-effective and robust for standard industrial environments.
Stainless Steel
Essential for corrosive, chemical, or hygienic environments.
Hot-Dip Galvanized Finish
Standard surface treatment for outdoor corrosion protection complying with international standards such as ASTM A123 or ISO 1461.
Standard Panels vs. Custom Fabrication
Standard Panels
Best suited for projects that can utilize predefined dimensions, offering faster delivery, simpler inventory management, and lower initial costs.
Custom Fabrication
Required for complex layouts, including cut-outs around pipes, irregular platform edges, edge banding, toe plates, and specialized stair treads. Providing a CAD drawing or grating schedule ensures high precision.
Essential Information for an RFQ (Request for Quotation)
When submitting an RFQ to manufacturers, including complete technical data speeds up the review process and prevents specification errors:
Product Type
Plain bar grating (welded or press-locked construction).
Dimensions
Panel length, width, quantity, and individual layout sizes.
Bearing Bars
Depth, thickness, spacing, and profile (plain vs. serrated).
Cross Bars
Type, spacing, and connection method.
Load Requirements
Uniform or concentrated load data, and maximum allowable deflection.
Material & Finish
Steel grade (e.g., Q235, ASTM A36, Stainless 304/316) and surface finish (bare, painted, or hot-dip galvanized).
Fabrication Details
Cut-outs, toe plates, edge banding, and stair tread specifications.
Documentation
Material test certificates (MTC), inspection records, and packing lists.
