  • Flat-type press-locked steel grating

Flat-type press-locked steel grating is an effective solution for a wide range of applications in the industrial and commercial sectors due to its sturdy construction, and low weight yet high strength. It is made from bearing bars that are pressed together with connecting crossbars, which form a rectangular grid pattern.

This type of grating can be easily installed without welding or bolting and offers high durability even in extreme conditions such as exposure to chemicals and heavy traffic. Flat-type press-locked steel grating is also highly resistant to corrosion and fire, making it ideal for use in environments where safety is paramount.

  • Serrated-style press-locked steel grating

Serrated edges give it an elegant design aesthetic that is also highly functional. This form of metal grating is available in various materials including mild carbon steel, hot dip galvanized steel, stainless steel, aluminum alloys, and exotic metals.

It can be fabricated into panels of any size or shape to meet individual requirements. The press-lock technology ensures superior joint security while the serration provides maximum load-bearing capacity without the need for additional fasteners.

  • Stainless press-locked steel grating

Stainless press-locked grating provides superior corrosion resistance. This type of grating is designed to be extremely lightweight while still providing strength and resilience under load.

Additionally, the versatility of it enables its use in a wide range of industries including water treatment plants, bi-directional flush surfaces, commercial kitchens, oil refineries, and chemical processing plants. With many benefits, stainless press-locked steel grating can provide a long-lasting and reliable option for global market needs.

  • Carbon press-locked steel grating

Its dense mesh pattern provides excellent slip resistance, making it safe for use in both wet and dry conditions. Carbon press-locked steel grating also has superior corrosion resistance due to its zinc coating, allowing it to last longer in harsher environments.

Additionally, the pressure-locked grating can be easily cut or welded into any shape or size needed for the application. With its strong yet lightweight design, carbon press-locked steel grating is sure to provide durable performance in any setting.

  • Galvanized press-locked steel grating

Galvanized press-locked steel grating is a construction material used for walkways, platforms, and other applications requiring drainage or air ventilation. It is composed of a welded frame with rectangular crossbars that are locked together at their intersections using a pressure-locking process.

This process creates an interlocking network that provides superior strength and durability compared to other materials such as aluminum and plastic. Its galvanized finish also provides more excellent resistance to corrosion and wear, making it suitable for outdoor use in many environments.

  • Painted press-locked bar grating

Painted press-locked steel grating is an ideal choice for light to medium-load applications that require a strong and durable material.

This type of grating offers a unique combination of strength, corrosion resistance, and durability while being visually attractive. It is available in a variety of colors according to clients’ requirements.

The painted finish also reduces the risk of dirt build-up which can cause damage over time. Additionally, its global press-locked gratings give it greater rigidity compared to welded alternatives. As such, painted press-locked steel grating is an economical and reliable solution for many industrial needs.

3. The applications of press-locked steel grating

Press-locked steel grating is an extremely versatile material that can be used in a wide variety of applications. These include walking and working surfaces, ramps, platforms, stair treads, machine guards, decking, fencing, security screens, and more. The open mesh cross bars design makes it easier to access the areas below without having to remove the grates.

It also allows for better air circulation and drainage while still maintaining structural integrity. In addition to its strength and durability characteristics, press-locked steel grating is also corrosion resistant making it ideal for areas with high exposure to moisture or other potentially corrosive elements.

Its ability to meet the needs of any application makes it an invaluable material for a variety of industries. Whether it is to construct industrial walkways, secure access points, or provide stable footing for heavy equipment, press-locked steel grating can be relied on to get the job done. It is no wonder why this material has been trusted for so many years.


Press-locked steel gratings provide an effective solution for pedestrian and industrial applications, offering a safe and durable alternative to other types of grating. The press-locking process ensures that the grating is securely locked together for maximum strength and stability, while its open grid structure allows for easy drainage of liquids and debris.

This makes it suitable for a wide range of uses such as walkways, platforms, and stair treads, as well as in wastewater treatment plants or refineries. Press-locked gratings are available in a variety of sizes and configurations to accommodate any project requirements.
