Galvanized corrugated steel pipe

Bridge hot-dip galvanized corrugated pipe is an industrial equipment used in pre-stressed concrete structures such as bridges. It is mainly used to transfer pre-pressurized stress and is available in two types: metal and plastic. Its structure is typically a corrugated tube body, featuring flexibility and resistance to deformation, which can meet the requirements of concrete pouring and steel strand insertion.

PRODUCT DETAILS

The iron metal corrugated pipes (i.e. corrugated pipe/corrugated steel plate culverts) produced by Forst Company are a new type of structural component made by using high-quality galvanized steel plates through the corrugation forming process. Compared with traditional concrete culverts and small bridges, this product has significant advantages such as light weight, high strength, convenient installation, and strong adaptability. The product is widely used in scenarios such as culverts, small bridges, passages, drainage pipes, tunnel linings, etc. in highway and railway engineering, and is also applicable to special engineering requirements such as temporary construction access roads, seepage wells, animal passages, etc. As a mature and reliable engineering material, the iron metal corrugated pipes can also be used for the reinforcement and renovation of existing concrete bridges and culverts, effectively extending the service life of the original structures.

Introduction of hot-dip galvanized highway guardrail beam 2025-09-29 16:33:21.034

Introduction of hot-dip galvanized highway guardrail beam Highway guardrail is the main form of semi-steel guardrail. It is a continuous structure with corrugated steel guardrail panels spliced with each other and supported by main columns. The vehicle has the function of absorbing energy when it collides, and it is not easy to be crashed, and at the same time it can play a good role in protecting the vehicle and the passengers. The bending of highway guardrails increases the aesthetics and increases the strength of the fence. Both; automatic production line extrusion molding, the surface is clean and undamaged, with strong anti-corrosion; mature surface treatment; anti-corrosion, anti-aging, and anti-corrosion It has the characteristics of sunlight, high and low temperature resistance, and the service life can reach 10-25 years in the outdoor environment. The product structure is simple, beautiful and practical, easy to transport and install, and has good anti-theft performance. It is less restricted by the actual terrain. The zone has strong adaptability and moderate cost, which is suitable for large-scale use.

Guardrail beam production process 2025-09-29 16:32:37.433

Step 1: Our factory use high quality new carbon coil grade of Q235B (S235JR), Q355B (S355JR), ASTM A 36 to produce the guardrail Step 2: Guardrail formed by mechanical extrusion Step 3: Hot dip galvanized on the guardrail surface Step 4：Passivation of passivation solution on the surface of the guardrail beam Step 5: Goods will be quality checked before send to customer.

What raw materials are the high-quality guardrail beam made of? 2025-09-29 16:31:09.903

The guardrail beam is a representative form of semi-rigid guardrail, which is a continuous structure with guardrails spliced to each other and supported by columns. It uses the deformation of the soil foundation, columns, and beams to absorb the collision energy, and forces the out-of-control vehicle to change direction and return to the normal direction of travel, preventing the vehicle from rushing out of the road, so as to maintain the safety of the vehicle and passengers and reduce the loss caused by traffic accidents . The guardrail beam uses S235JR low-carbon steel or S355JR manganese steel with relatively strong strength and toughness. It has good elasticity and has a strong ability to absorb collisions when it encounters collisions. process, re-hot-dip galvanizing to achieve the effect of improving the appearance of anti-corrosion design. The accessory bolts are made of S235JR or S355JR except for splicing bolts M16-35 which are made of No. 45 #steel. After the corrugated guardrail is processed by hot-dip galvanizing process, it can be used for a longer time in the field environment, is resistant to aging, and can resist the corrosion of wind and rain. The service life can reach 15-30 years under normal conditions without external damage.
