Press Locked Steel Grating is a high-precision engineered grating system designed for projects that require both structural strength and architectural appearance.
It is manufactured under strict international standards including ASTM A123 and YB/T 4001.1, ensuring consistency, durability, and compliance with global engineering requirements.
Unlike traditional welded systems such as welded steel grating, this pressure-locked bar grating delivers a cleaner surface, tighter tolerance, and a more refined visual effect—making it especially suitable for visible architectural installations.
👉 This makes it ideal for projects where appearance is as important as function.
👉 Compared with welded steel grating, it avoids welding distortion and maintains a more precise finish.
👉 We support full technical coordination from design to installation stage.
Press Locked Steel Grating (also known as press-fit grating) is fabricated using flat bars for both bearing bars and cross bars. Each bar is precisely notched, then interlocked in a cross-insertion configuration and welded at alternating intersections.
This controlled welding pattern helps minimize deformation caused by thermal expansion during fabrication.
Compared with welded steel grating, the key differences are:
This is why many architects prefer it for premium architectural applications, while welded grating remains dominant in heavy industrial environments.
We manufacture standard and customized configurations based on project requirements.
👉 Custom specifications are available via custom steel grating.
Depending on project environment, we offer multiple material solutions:
Provides strong corrosion resistance for outdoor and industrial environments
→ galvanized steel grating
Ideal for high-end architectural projects or corrosive environments
→ stainless steel grating
Fully tailored fabrication based on drawings and engineering requirements
→ custom steel grating
This type of grating is widely used in both architectural and commercial engineering projects where appearance matters.
Used in modern building envelopes and decorative facades
Creates a strong geometric visual effect while maintaining ventilation
Reduces direct sunlight while allowing airflow
Improves energy efficiency in modern buildings
Used as suspended ceiling systems in commercial spaces
Provides an industrial-modern aesthetic style
Suitable for airports, exhibition centers, and commercial buildings
Combines safety performance with architectural appearance
(For industrial flooring alternatives, see metal floor grating)
We are not just a steel grating supplier—we are a long-term manufacturing partner for engineering projects.
Every batch of Press Locked Steel Grating is inspected under strict quality procedures:
Third-party inspection available (SGS, BV, etc.) before shipment.

Q1：What information should I provide for a Press Locked Steel Grating quotation?
A：Please provide the panel size, bearing bar size, grid opening, material, surface finish, quantity, application, and any load or installation requirements. If you have drawings or layout plans, we can review them and provide a more accurate quotation with technical suggestions.
Q2：Can press locked grating panels be customized for non-standard projects?
A：Yes. Press locked grating panels can be customized according to project drawings, including panel dimensions, grid openings, bearing bar sizes, cut-outs, edge treatment, surface finish, and installation requirements. Custom fabrication is suitable for architectural facades, screens, ceilings, walkways, and special engineering structures.
Q3：What grid openings are available for pressure locked bar grating?
A：Common grid openings include 33×33 mm, 33×11 mm, 30×50 mm, 40×40 mm, 50×50 mm, and 100×100 mm. The final opening size should be selected according to appearance requirements, ventilation needs, walking safety, load capacity, and the overall architectural design.
Q4：Is Press Locked Steel Grating better for architectural projects than welded grating?
A：Press Locked Steel Grating is often preferred for architectural projects because it has no visible welding beads, a cleaner surface, better grid alignment, and a more refined appearance. Welded grating is usually more common for heavy industrial flooring, while press locked grating is better for visible design-focused areas.
Q5：Can galvanized press locked grating be used outdoors?
A：Yes. Galvanized press locked grating can be used for outdoor facades, sunshades, platforms, walkways, and building screens. Hot-dip galvanizing improves corrosion resistance and helps protect the surface during long-term exposure. For coastal or harsh environments, coating requirements should be confirmed before production.
Q6：When should I choose stainless steel grating for my project?
A：Stainless steel grating is recommended for high-end architectural projects, corrosive environments, humid areas, or applications where appearance and long-term durability are important. It is commonly used in commercial buildings, public spaces, decorative structures, and projects requiring a cleaner surface finish with stronger corrosion resistance.
Q7：Can press locked grating be used for walkways and platforms?
A：Yes. Press locked grating can be used for premium walkways, platforms, airports, exhibition centers, commercial buildings, and public access areas. For walking applications, the bearing bar size, grid opening, span, surface type, and load requirement should be checked to ensure safety and stability.
Q8：Is serrated surface available for anti-slip requirements?
A：Yes. Serrated surface options are available when better slip resistance is required. Serrated press-fit grating is suitable for areas exposed to rain, moisture, or foot traffic safety concerns. For architectural projects, the choice between plain and serrated surface should balance appearance, safety, and application conditions.
Q9：How do you control panel flatness and grid alignment?
A：Panel flatness and grid alignment are controlled through precise slotting, dimensional inspection, and strict production checks. Each batch can be inspected for grid spacing, bar thickness, alignment, surface condition, and overall panel accuracy before shipment to reduce installation problems on site.
Q10：Can you provide CAD drawings before production?
A：Yes. CAD drawings can be provided based on your project dimensions, installation layout, and technical requirements. Drawings help confirm panel size, grid direction, cut-outs, fixing details, and quantity before production, which is especially important for architectural facades, ceilings, sunshades, and customized grating systems.
Q11：What quality documents can be supplied with the order?
A：We can provide material certificates, Mill Test Reports, dimensional inspection records, and galvanizing inspection information when required. For project orders, third-party inspection such as SGS or BV can also be arranged before shipment to confirm quality, coating condition, and specification compliance.
Q12：How is Press Locked Steel Grating packed for export?
A：Press Locked Steel Grating is usually packed with reinforced bundling, edge protection, and export-ready packaging to reduce surface damage, deformation, and impact during transportation. Packaging can be optimized for container loading and long-distance delivery, especially for architectural panels that require better surface protection.
Watch our factory live footage to see how press locked steel grating is manufactured with precise bar alignment, high-pressure locking, and careful dimensional control.
Unlike traditional welded grating, press-locked steel grating is produced by pressing cross bars into pre-slotted bearing bars under mechanical pressure. This creates a clean, uniform grid structure without visible welding marks, offering both structural stability and a refined architectural appearance.
This precision-made grating provides a clean grid appearance, excellent structural stability, and flexible design options for architectural facades, walkways, platforms, and decorative industrial applications.
