Carbon steel bridge guardrail is an important safety feature that can prevent vehicles from running off the road and falling off the bridge. Made from high-quality carbon steel, these guardrails are designed to withstand impact and provide a strong barrier for drivers. They are also corrosion- resistant and durable, making them an ideal solution for high-traffic areas. Installing a carbon steel bridge guardrail not only protects motorists but also enhances the appearance of the bridge, adding to its longevity and aesthetic value.  The road anti-collision guardrail is mainly composed of guardrail posts and anti-collision beams. The main raw materials of the guardrail post are welded and assembled from Q series steel plates (Q195-235/16Mn) and aluminum alloys or casted with steel. The finished products are galvanized and sprayed or sprayed with Buddha carbon paint to make the guardrail products have acid resistance It has a series of advantages such as alkali corrosion resistance, no rust in the sun and rain, no delamination, durability and no discoloration, luxury and nice looking.

Customized Thrie-Beam Highway Guardrail may include the size and shape of the beams, the spacing between the posts, the height of the guardrail, and the material used for the posts. Other customization options may include the color of the guardrail and the addition of reflective strips to improve visibility at night. The specific design requirements for a customized Thrie-Beam guardrail will depend on the specific site conditions, traffic volume, and other factors that impact the safety of the roadway. Processing of Customized Thrie-Beam Highway Guardrail Processing of Galvanized Steel thrie beam Guardrails can be divided into two major steps. 1. First, to fabricate the steel sheet into two or three wave panels through the professional production equipment; 2. Then to put the steel sheet into the zinc dipping stove for hot dipped galvanizing.

This hot-dip galvanized steel W beam is one of the highway safety products from DACHU conforms to AASHTO and ASTM specifications. Hot-dip galvanized steel W beam is one of the most popular metal beams used in construction projects today. This product provides excellent protection against corrosion, weathering, and abrasion, making it ideal for any outdoor project. Hot-dip galvanizing is a process used to create a bond between the metal alloy and a zinc coating, which not only increases the product’s durability and resistance to corrosion but also offers superior corrosion protection when compared to other materials. Hot-dip galvanized steel W beams are available in a wide range of sizes and are ideal for highway guardrails, farm fences, and many other outdoor structures.

5W ~ 5000W Good high temperature load characteristics, strong overload capacity, moisture resistance, vibration resistance, and high power.

1/4W 1/2W 1W 2W 3W 4W 5W 7W 10W The function is the same as the wire-wound resistor, and it can be installed by the chip mounter, which is more efficient and less costly.

1/8W 1/6W 1/4W 1/2W 1W 2W 3W 4W 5W Metal film resistors are the most widely used resistors so far. They have high precision, stable performance, simple and lightweight structure. They play an important role in the electronics industry and military aerospace fields with high precision requirements. They use high-temperature vacuum coating technology to tightly attach nickel-chromium or similar alloys to the surface of the porcelain rod to form a film, and then cut and adjust the resistance value to achieve the final required precision resistance value, then add appropriate joint cutting, and coat the surface with epoxy resin for sealing and protection.

1/8W 1/6W 1/4W 1/2W 1W 2W 3W 4W 5W Carbon film resistor is a kind of film resistor. It is made by high temperature vacuum coating technology to attach carbon tightly to the surface of porcelain rod to form carbon film, then cut with appropriate joints, and apply epoxy resin on the surface for sealing and protection. Its surface is often coated with green protective paint. The thickness of carbon film determines the size of resistance, and the resistor is usually controlled by controlling the thickness of film and cutting grooves. Carbon film resistor is also called "thermally decomposed carbon film resistor". It is a kind of thin film resistor in which carbon is deposited on the substrate by high temperature thermal decomposition of hydrocarbon in vacuum. It is low in price, stable in performance, and has a wide range of resistance and power.

This type of resistor is made by decomposing and depositing a hydrolyzed metal salt solution (such as tin tetrachloride and antimony trichloride) on the surface of hot glass or ceramic. The performance of resistors varies greatly depending on the manufacturing conditions. The main characteristics of this resistor are high temperature resistance, an operating temperature range of +140~235℃, overload use in a short time, a resistance temperature coefficient of ±3×10-4/℃, and good chemical stability. This resistor has a low resistivity, and the resistance of a low-power resistor does not exceed 100 kilo-ohms.

1/4W 1/2W 1W 2W 3W 4W 5W Wirewound resistors are a type of fixed resistor. Wirewound resistors are made of resistance wire wound on an insulating frame. Resistance wire is generally made of nickel-chromium, manganese-copper and other alloys with a certain resistivity. The insulating frame is made of ceramics, plastics, metals coated with insulating layers and other materials into various shapes such as tubular and flat. The resistance wire can be wound on the frame in one layer or multiple layers according to needs, or non-inductive winding can be used. Wirewound resistors are mainly used for voltage division, voltage reduction, current shunting and load in AC and DC circuits such as precision instruments, telecommunication instruments, and electronic equipment.
