  • Stainless Steel Grating

    Stainless Steel Grating

    Stainless steel grating, as its name suggests, is a metal grating made of stainless steel material. Stainless steel grating is commonly made of materials such as SUS304, SUS316L, S309, 2205, SMo250, etc. Stainless steel grating has features such as corrosion resistance and aesthetics. Currently, stainless steel grating is commonly used in many places such as subways, shopping malls, hotels, food factories, and amusement parks. Common types of stainless steel grating include: G303/30/100; G305/30/100; G253/30/100: G323/30/50, etc.

  • Grating Stairs

    Grating Stairs

    There are four types of staircase steel grating steps, T1, T2, T3, and T4. T1 steps are ordinary and low-cost, consisting of load-bearing angle iron and crossbars arranged at regular intervals in a weft pattern. They are typically welded and fixed to the steel grating and then hot-dip galvanized for surface treatment. Due to their relatively low price, they are welcomed by many steel grating customers. T2 staircase steel grating steps are fixed on both sides with angle iron and crossbars arranged at regular intervals in a weft pattern, with side plates and bolts. They are mainly used on steel stairs and are easy to install. T3 staircase steel grating steps are based on the T1 steps, with a front protection plate added to the angle iron direction. The front protection plate is typically made of花纹plate and increases the non-slip performance of the steel grating steps. T4 staircase steel grating steps are equivalent to a combination of the T2 steps and the T3 steps. They have a front protection plate and installation slots on both sides. The welded staircase steel grating steps are directly welded to the staircase beam without adding side plates to the steps themselves, which is relatively economical and durable but not easy to disassemble. The bolted staircase steel grating steps require thick side plates on both sides that are drilled with holes for installation using bolts to fasten them, which allows for recycling and reuse. Customers can customize their orders based on their actual needs and use appropriate types of steel grating steps to create various sizes to match their corresponding stairs.

  • Grating Sewer Cover

    Grating Sewer Cover

    Characteristics of Sewer Cover Products:

    Surface treatment with hot-dip galvanization: Strong rust prevention ability.
    Advanced design in China: The cover of the drainage channel is connected with the frame using hinges, which is theft-proof, safe, and easy to open.
    Beautiful appearance: Simple and concise lines, silver color surface, modern concept.
    Optimal drainage performance: The mesh hole size provides for maximum water drainage area, which is 83.3% more than that of cast iron.
    Material cost-effectiveness: In large spans and heavy loads, the cost is lower than cast iron, and it can save the cost of replacing cast iron covers that are stolen or crushed.
    High-strength carbon steel: The steel grating has high strength and toughness, which is much higher than cast iron, making it suitable for environments with large spans and heavy loads such as docks and airports.
    Multiple product varieties: Meets the needs of different environments, loads, spans, and shapes required, and can be made according to customer-provided sizes and shapes.

    The purpose of the rectifier grid: In recent years, with the continuous development and progress of technology, the domestic boiler manufacturing industry has also made rapid development. Small-capacity boilers have gradually been eliminated, and large-capacity, high-parameter boilers have become the mainstream of the current power industry. On the boilers used nowadays, denitrification requires the use of large-area rectifier grids. Specification and size of the rectifier grid: The commonly used steel grating plates generally have a height of less than 60mm. The rectifier grids used in China generally have a height of more than 300mm and a thickness of more than 3mm. The mesh size is between 100mm/321mm, and the plates are produced by opening and inserting full welding, which has strict requirements in welding requirements and other aspects. The size varies, generally with a long length of about 10 meters and a width of about 3 meters. As the length is long, the processing and production cycle is relatively long. It is recommended that customers pre-order in advance, and the size is generally customized according to the drawing. Material of the rectifier grid: The rectifier grid for boilers must be made of Q345材质 flat steel, and cannot use Q235 material. Surface treatment: As the rectifier grid is relatively heavy in weight, the surface treatment methods are relatively simple, generally surface anti-rust paint treatment, and then one surface paint is applied.

  • Inserted Steel Grating

    Inserted Steel Grati…

    Pressure-Locked Grating: This type of grating is manufactured by using ordinary carbon flat steel, stainless steel, brass, aluminum sheets, which are processed through various steps including opening slots (holes), inserting and locking, welding, and finishing. It is called pressure-locked grating when the cross points of the load-bearing flat steel and the transverse flat steel are pressed into each other under pressure to fix them. The transverse flat steel used for pressure-locked grating is also ordinary carbon flat steel.
    Classification: a. Conventional Type Pressure-Locked Grating: This type of grating features a transverse flat steel with a lower height than the load-bearing flat steel. b. Integral Type Pressure-Locked Grating: This type of grating has load-bearing flat steel and transverse flat steel of the same height, with the slot depth being one half of the load-bearing flat steel. c. Shade Type Pressure-Locked Grating: This type of grating has load-bearing flat steel with a 30° or 45° sloping slot, and the transverse flat steel is compressedively formed.
    Load-Bearing Flat Steel Spacing: The spacing between load-bearing flat steel is usually 30mm, 40mm, 50mm, 100mm, etc.
    Transverse Flat Steel Spacing: The spacing between transverse flat steel is usually 30mm, 40mm, 50mm, 100mm, etc.
    Characteristics: Pressure-Locked Grating not only includes the high strength, corrosion resistance, and maintenance-free characteristics of pressure-welded grating, but also has unique features of uniform combination, lightweight structure, exquisite appearance, and natural harmony.
    Applications: Pressure-Locked Grating is widely used in civil and commercial buildings, theatres, subways, municipal engineering projects such as advertising signs and various covers for indoor and outdoor decoration and renovation projects, platforms and corridors, ventilation windows (wells), etc.

  • Handrail

    Handrail

    Spherical Railing is factory-produced using ball joints, ordinary hot-dipped galvanized steel or stainless steel, with novel and beautiful appearance, easy installation, solid durability, and no maintenance required. It is widely applicable for walkways, platforms, stairways, and barriers in various fields such as mining, power, petrochemical, machinery, light industry, shipbuilding, railways, roads, bridges, docks, schools, water treatment plants, and gardens. Spherical Railing complies with international standards such as British BS6399 and BS6180, Australian 1650-1985, as well as Chinese Standard 4053.3-83.

    Spherical Railing Details:

    Pipe Sizes: The carbon steel sizes are listed before the brackets and the stainless steel sizes are inside the brackets in the table above.

    Pillar Spacing: Mainly three sizes: 1000mm, 1200mm, and 1500mm.

    Railing Height:

    (1) Double Poles:

    A: Horizontal Railing: The minimum height of the handrail is 1100mm.

    B: Staircase Slope Railing: The minimum vertical height of the handrail is 900mm.

    (2) Triple Poles: Usually 1200mm.

    (3) Single pole or more than three poles are designed according to the requirements.

    Method of Connecting Crossbars and Pillars:
    <1> Generally welded and fixed method is used, and local rust prevention treatment is applied to the welding position.

    <2> It can also be fixed with set screws or pins. During installation, corresponding installation holes need to be drilled on site.
