Press-Locked Steel Grating Factory

Press-lock steel grating, also known as plug-in steel grating, is a steel grating made of flat steel and crossbars of a certain size through grooving, plug-in, press-locking, welding, finishing and other processes. The following is a detailed introduction to press-lock steel grating.

 

Press-lock steel gratings are widely used in platforms, walkways, stair treads in power plants, steel mills, chemical plants, oil refineries, etc. Ditch covers, cable trench covers, parking platforms, subway and urban rail platforms, tunnel vents, docks, mines, sewage treatment plants, airports, ports and other places.

According to the production form of the product, Press-Locked Steel Grating can be divided into:

  • Ordinary type: 

It is formed by cutting grooves in the load-bearing flat steel and then pressing and locking it with the cross bar flat steel. The length is usually less than 2000mm.

  • Integral type: 

The load-bearing flat steel and the cross bar flat steel have the same height, and the groove depth is 1/2 of the load-bearing flat steel, the length is usually less than 2000mm

  • Sunshade type: 

The load-bearing flat steel is slotted at 30° or 45°, and the slotted flat steel is slotted and pressed into shape. Steel gratings with other spacing and specifications can be processed according to different needs. Ordinary carbon steel, stainless steel, aluminum and other materials can be used.

  • Heavy-load type: 

The high flat steel and the cross bar flat steel are interlocked and pressed into shape, which is suitable for occasions with high spans and loads.

Characteristics of Press Lock Grating

Structural performance

  • High strength and light structure

    Made of high-strength steel, it has high tensile and compressive strengths and can withstand large loads and impact forces; at the same time, the unique structural design makes it relatively light and easy to carry and install.

  • Good lateral force transmission

    Under the same load conditions, the press-lock steel grating can transmit better lateral forces, and less materials are required, which can effectively prevent the instability and tilt of large-sized load-bearing flat steel.

  • Strong bearing capacity

    Its mesh structure, load-bearing load and service life are comparable to those of press-welded gratings, and it is suitable for various places that need to withstand heavy loads, such as power plant platforms, sewage treatment plant maintenance platforms, parking lot platforms, etc.


Appearance design

  • Beautiful appearance

    The surface is glossy, the design is simple and generous, the lines are smooth, and it can be coordinated with the surrounding environment, adding beauty to buildings and projects. It can be used for indoor and outdoor decoration, ceilings, advertising plaques and other places.

  • Smooth surface

    The flat steel adopts a compression lock structure, which makes the appearance of the steel grating very smooth and flat. The surface is also very clean and clean. It is not easy to accumulate dirt, rain, snow and water. It has strong self-cleaning ability and is easy to maintain.


Installation and maintenance

  • Easy to install and disassemble

    Light weight and simple structure, no complex tools and equipment are required during the installation process, which can greatly save manpower and time costs; at the same time, it is also convenient for later disassembly and replacement.

  • Strong anti-corrosion ability

    Generally after hot-dip galvanizing, spraying and other anti-corrosion treatments, it can effectively resist corrosion from the atmosphere, water, chemicals, etc., extend the service life, and maintain good performance under harsh environmental conditions. The service life of 30-50 years reduces the cost of frequent replacement and maintenance.


Functional characteristics

  • Good ventilation and light transmittance

    The surface of the steel grating is a mesh structure with high permeability. It can effectively ventilate, lighten and dissipate heat. It can be used in places that require good ventilation and lighting conditions, such as warehouses, workshops, etc.

  • Good anti-slip and explosion-proof properties

    The flat steel and crossbars on the surface form a certain concave and convex texture, which increases the friction and has good anti-slip properties, which can effectively prevent people from slipping; at the same time, it can also play a certain explosion-proof role in some flammable and explosive places.

  • Diverse specifications

    The specifications of the flat steel spacing and crossbar spacing are rich and varied. For example, the bearing flat steel spacing is usually 30mm, 40mm, 50mm, 100mm, etc., and the crossbar spacing is usually 30mm, 40mm, 50mm, 100mm, etc., which can meet the various needs of different users and different places.


Application areas of Press Lock Grating

  • Residential buildings, apartments, etc.

  • Shopping malls, supermarkets, hotels, exhibition halls, theaters, etc.

  • Transportation facilities

  • Urban public areas

  • Factory workshops

  • Chemical, petroleum, electricity and other industries

Classification of Press-Locked Steel Grating

  • Materials: low carbon steel and stainless steel.

  • Surface treatment: galvanized, painted or powder coated.

  • Surface type: smooth surface and serrated surface

  • Serrated surface type:

  1. PR/S1: Trapezoidal teeth on the bearing bar.

  2. PR/S2: Trapezoidal tooth both on the bearing bar and cross bar with the highest non-slip performance. In this three types. it is most popular.

  3. PR/S3: The non-slip tooth is applied to the connect components. It has the lowest non-slip performance.
