Serrated Bar Grating

Serrated Bar Grating

Serrated bar grating, as the name suggests, is a type of steel grating made from serrated flat steel. In addition to possessing the characteristics and applications of regular steel grating, serrated bar grating also offers strong anti-slip capabilities, making it particularly suitable for wet, slippery environments such as offshore oil platforms. The serrated surface of the grating is achieved through hot-dip galvanization, providing excellent rust resistance. This product can be hinged to the frame of drain covers, ensuring theft prevention, safety, and easy opening.

Raw material of serrated bar grating (Customizable)

Commonly available in various specifications such as 253, 255, 303, 305, 323, 325, 403, 404, 405, 503, 505, 605, 705 steels, etc. The main type used is longitudinally sheared flat steel, which is obtained by cutting steel plates. Serrated flat steel is similar to regular flat steel but differs in having uneven teeth on one side, primarily for anti-slip purposes.

Advantages of serrated bar grating

  • Serrated bar grating is manufactured using high-strength carbon steel, which gives it exceptional strength and toughness surpassing that of cast iron.
  • It can be used in environments with large spans and heavy loads, such as docks and airports. This product features large mesh openings, allowing for efficient drainage with a water leakage area of 83.3%, more than twice that of cast iron.
  • Its appearance is aesthetically pleasing, with clean lines and a silver-colored modern design.
  • In terms of materials, serrated bar grating is more cost-effective than cast iron for large spans and heavy loads, as it eliminates the need for replacement due to theft or crushing.

Manufacturing Process of Serrated Bar Grating

Raw Material Selection: The initial step is to choose the appropriate raw materials, such as carbon steel, stainless steel, or aluminum, based on the desired strength and corrosion resistance.

Material Preparation: The selected raw material is prepared by cutting it into suitable sizes and shapes according to the grating design requirements.

Bar Fabrication: Serrated profiles are created on the bars using specialized machinery that can cut or notch them to provide enhanced slip resistance.

Bar Assembly: The serrated bars are assembled together using methods like welding, riveting, or swaging to form the grating panel.

Surface Treatment: The grating panel undergoes surface treatments like hot-dip galvanizing, electroplating, or powder coating to improve durability and corrosion resistance.

Applications of Serrated Bar Grating

Serrated bar grating finds wide applications in various fields, including construction, transportation, and maritime industries.

In construction, it can be used for structures such as pedestrian bridges, walkways, staircases, and ventilation openings, providing excellent slip resistance and durability.

In transportation, it is commonly used in roads, bridges, and subway stations to reduce wear caused by heavy vehicles.

In maritime applications, serrated bar grating is essential for ship cabins and docking areas, offering higher stability and safety due to its high strength and slip resistance.

Tips for Selecting Serrated Bar Grating

When selecting serrated bar grating, it is important to consider the thickness of the flat bars and the height of the serrated teeth.

Choose the appropriate specifications based on factors like load capacity, climate conditions, and the required level of slip resistance and safety.

Inquire about the manufacturing process and quality assurance from suppliers to ensure the product’s reliability and quality.

Also, ask about the surface coating thickness and treatment methods to ensure compatibility with the external environment. Finally, pay attention to the brand and after-sales service, opting for reputable manufacturers with good reputation.

Dimension and performance of serrated bar grating

Serrated Bar Grating Dimensions
The spacing and height of serrated bar grating are key parameters that determine its strength and load-bearing capacity. In engineering applications, common spacing options include 30mm, 40mm, 50mm, 60mm, and so on, while the height usually ranges from 3mm to 5mm.

Serrated bar grating is a commonly used construction material known for its excellent slip resistance and load-bearing capacity. It finds wide applications in industrial, commercial, civil construction, bridge, and road sectors. The dimensions of serrated bar grating are among its important parameters. Let’s delve into the details of serrated bar grating dimensions.

Typically, the dimensions of serrated bar grating are described by three parameters: length, width, and thickness. Length refers to the long side length of the serrated bar grating, usually ranging from 1 meter to 6 meters. Width denotes the width of the serrated bar grating, typically ranging from 0.5 meters to 1.5 meters. Thickness represents the thickness of the serrated bar grating, generally ranging from 3 millimeters to 10 millimeters. The specific dimensions can be chosen based on the intended use requirements.

The dimensions of serrated bar grating have a significant impact on its performance. The size of length and width directly affects the load-bearing capacity and range of application. Generally, larger length and width result in higher load-bearing capacity and broader suitability for various applications. However, excessively large dimensions can increase the weight, cost, and installation difficulty of serrated bar grating.

The thickness of serrated bar grating also plays a crucial role in its slip resistance and load-bearing capacity. In general, thicker grating offers greater load-bearing capacity, but it also increases the weight and cost. Moreover, thickness influences the slip resistance of serrated bar grating, as excessive thickness might affect its anti-slip effectiveness.

How to choose the right size of serrated bar grating?

Spacing of 30mm

Spacing of 30mm is a commonly used type of serrated bar grating that finds applications across various industrial sectors. The center-to-center distance of the loaded flat steel in this series is 30mm, conforming to American standards. This series is highly resistant to surface impacts and is widely used in power plants, refineries, sewage treatment plants, granaries, chemical plants, highways, airports, docks, platforms, walkways, drain covers, stair treads, etc. The serrated bar grating in this series is particularly suitable for wet and slippery areas, especially offshore oil platforms.
