Galvanized Steel Bar Grating

Product Description

A type of steel product that is widely used is galvanized steel bar grating. Featuring a grid-like structure with a square pattern in the middle, it is formed by crossing flat steel bars at fixed intervals, followed by welding them together. It is ideal for applications such as drain covers, steel structure platform plates, and steel ladder stair treads. The crossbars can either be twisted square steel or flat steel, depending on the specific needs of the project.

Galvanized steel bar grating is a type of grating typically made of carbon steel. The surface is either hot-dip galvanized or painted to prevent oxidation. Alternatively, it can be made of stainless steel, although the cost of this option is typically higher. When compared to painted steel grating, hot-dip galvanized steel grating offers superior anti-corrosion performance. Hence, it is the preferred choice in most cases. Despite the availability of stainless steel grating, hot-dip galvanized steel grating remains the most popular option due to its favorable cost-performance ratio.

Classification of Galvanized Steel Bar Grating

Hot-dip galvanized steel grating can be categorized based on the production process into pressure welding and pressure-locking varieties.

The load-bearing flat steel used in grating can be categorized in three ways based on its shape: I-type hot-dip galvanized steel grating, serrated hot-dip galvanized steel grating, and plain hot-dip galvanized steel grating. Each of these types provides unique benefits depending on their specific design.

Installation Method

There are two methods for installing galvanized steel bar grating - welding and mounting clamp fastening. Both options offer secure and reliable installation for this durable material. Whether welded or clamped, galvanized steel bar grating can withstand heavy loads, harsh environments, and daily wear and tear. Choose the installation method that best suits your needs and enjoy the benefits of this versatile and long-lasting material.

Welding comes with the benefit of creating a permanent and secure attachment that will not loosen over time. Specifically, the weld should be placed on the first flat steel of every corner of the steel grating, with a minimum length of 20mm and height of 3mm. This ensures a strong and reliable connection for the structure.

Installation clamps offer a significant advantage because they do not cause any harm to the hot-dip galvanized layer and can be effortlessly detached. The recommended number of installation clamps per board is four, and this figure increases proportionally with the board length. To prevent any accidents, it is advisable to weld the screw heads straight onto the beam instead of using the lower clamp. This will guarantee that the steel grating will not slip off the beam due to any loosening of the installation clamps, ensuring maximum safety.

Usage

Platforms, walkways, and various other structures benefit greatly from the use of galvanized steel bar gratings. These gratings find widespread applications in diverse industries ranging from power plants and chemical plants to oil refineries and steel plants. Additionally, they are utilized in paper mills, machinery plants, cement plants, and even municipal engineering projects. Galvanized steel bar gratings are also commonly employed in sewage treatment plants, environmental sanitation engineering, and other similar projects. Their versatility makes them suitable for a wide range of purposes, such as trestles, ditch covers, manhole covers, ladders, fences, and guardrails.
