Painted steel bar grating is a product that undergoes painting treatment on the surface of metal grating. This treatment can prevent oxidation of the steel grating and extend its service life while providing a variety of color options.It has low manufacturing costs, moderate rust resistance,and is suitable for occasions with less strict requirements for humidity and corrosion.

Also described as Painted Metal Grating, this product is commonly used for indoor industrial platforms, equipment access areas, maintenance walkways, mezzanines, stair treads, machine bases, and protected architectural metalwork.Some customers also choose to spray an additional layer of paint on the galvanized steel plate. in this way,even if there is an issue with the paint layer the underlying galvanized layer can ensure the basic performance of the steel grating, so that the steel grating can still function well even in harsh environments.

Why Choose Painted Steel Grating?

• Color matching for industrial equipment and structures
  Select a suitable coating color for machinery, guardrails, safety zones, platforms, or architectural metalwork.

• Cost-effective for suitable environments
  Painted grating can be a practical choice for dry indoor areas and protected applications where long-term heavy-duty corrosion resistance is not the primary requirement.

• Flexible grating structure options
  Available with flat bars, I-bars, or serrated bearing bars according to the loading condition, panel weight requirement, and slip-resistance needs.

• Custom fabrication support
  Panels can be reviewed for cut-outs, irregular shapes, edge banding, stair treads, access openings, and drawing-based production.

• Easy visual identification
  Color-coded grating can help distinguish maintenance routes, equipment zones, restricted areas, access platforms, and safety walkways.

Various appearance colors. Commonly used colors include black paint, as well as red, white, blue, gray, etc

Elegant appearance. Painting the steel grating can improve its appearance, making it more visually appealing

Painted steel grating is suitable for places with low humidity and corrosion requirements, including:

Industrial: Factories, oil refineries, chemical plants.  

Infrastructure: Stair treads, catwalks, bridges, drainage covers.  

Architectural: Decorative facades, sunshades, rooftop platforms.  

Public Spaces: Parks, pedestrian walkways, subway grates.  

Application Boundary

Painted grating should not automatically be treated as the preferred solution for:

• Offshore structures

• Coastal or salt-spray environments

• Continuous outdoor exposure

• Highly humid areas

• Chemical processing zones

• Wastewater facilities

• Long-term wet or corrosive environments

For these applications, please review Galvanized Steel Grating, Stainless Steel Grating, or other corrosion-resistant alternatives before final selection.

Color and Coating Customization

Color is often one of the main reasons customers choose painted steel grating. It can help match an industrial equipment line, distinguish safety zones, or improve the appearance of visible steel structures.

Custom color requirements may include:

• Black, gray, blue, red, yellow, white, or other confirmed standard colors

• Customer-provided color sample or coating reference

• Safety-color identification for access routes or restricted zones

• Matching color for machinery, guardrails, handrails, or steel frames

• Different colors for separate project zones or panel groups

• Protective packing for visible painted surfaces

Before confirming a color order, please specify the required color standard, gloss expectation, application environment, and whether the panel will be exposed to outdoor weather, abrasion, cleaning chemicals, or frequent traffic.

Custom Fabrication by Drawing

Canri Wire Mesh can review drawing-based Painted Steel Grating requirements to reduce unnecessary cutting and welding on site.

Custom fabrication options may include:

• Panel length and width

• Bearing-bar size and spacing

• Cross-bar spacing

• Plain or serrated surface

• Pipe and column cut-outs

• Handrail-post openings

• Equipment support openings

• Notched corners and irregular panel shapes

• Edge banding

• Stair treads and landing panels

• Removable access panels

For accurate quotation, please send a panel schedule, CAD drawing, PDF drawing, BOQ, or reference photo.

Coating Quality Control

For painted grating orders, coating appearance and surface protection should be reviewed together with grating dimensions and fabrication details.

Typical quality-control points may include:

• Material verification

• Bearing-bar and cross-bar spacing inspection

• Panel length, width, and cut-out inspection

• Weld appearance inspection

• Surface cleaning or preparation confirmation

• Color confirmation before production

• Coating appearance inspection

• Checks for missed coating areas, runs, bubbles, scratches, or exposed edges

• Coating thickness inspection

• Adhesion inspection 

• Pre-shipment photos

• Third-party inspection coordination 

For visible or decorative applications, customers should confirm acceptable color variation, gloss level, edge appearance, and packing protection before mass production.

Packing and Delivery

Painted steel grating requires suitable handling and packing to reduce surface scratches during loading, transport, and unloading.

Recommended packing considerations include:

• Palletized panels

• Steel strapping

• Protective separation between painted panels [confirm available method]

• Corner protection for visible edges [confirm available method]

• Packing labels by panel number or project zone [confirm available service]

• Export packing suitable for sea shipment

Order Information

• Payment Terms: T/T

• Packaging: Palletized and steel-strapped for sea shipment

• Custom Order Lead Time: Based on grating type, color, coating system, fabrication complexity, quantity, and packing requirements

Frequently Asked Questions

Q：Is painted steel grating suitable for outdoor use?

It may be suitable for selected protected outdoor applications when the coating system is specified for the actual environment. For long-term outdoor exposure, coastal conditions, high humidity, or corrosive environments, galvanized or stainless steel grating may be more appropriate.

Q：Can I choose a custom color?

Yes. Please provide the required color reference, such as a RAL code, customer color sample, or project color specification. Available paint systems and color ranges should be confirmed before order placement.

Q：Can painted steel grating be used for industrial platforms?

Yes. It is commonly used for indoor platforms, equipment access areas, stair treads, mezzanines, and maintenance walkways. Final bearing-bar size and spacing should be confirmed according to span and load.

Q：When should I choose serrated painted grating?

Serrated grating may be considered where improved traction is needed, such as dusty, oily, or occasionally wet industrial access areas. The final surface should be selected according to the actual operating conditions.

Q：Can you fabricate painted grating from my drawings?

Yes. Send your dimensions, quantity, cut-outs, panel schedule, support layout, color requirement, and reference drawings for review.

Q：Can painted steel grating replace galvanized steel grating?

It can be a practical alternative in dry, indoor, low-corrosion, or color-sensitive applications. It should not be considered a direct replacement for galvanized grating in all outdoor or corrosive environments.
