Guardrail end caps are pieces installed on the traffic-facing edge of guardrails to protect drivers who crash into them. Without properly functioning end caps, the sharp end of the guardrail could easily puncture the passenger compartment, injuring any occupants of the vehicle. The end cap is a complex piece of safety technology that accomplishes two tasks at once. First, as the accident occurs, there is a flat slot on the backside of the cap. The force of the car pushes the rail itself through the slot, flattening it out from a stiff metal structure into a more flexible ribbon that cannot pierce the vehicle. At the same time, a blade on the back of the cap uses the accident’s force to dislodge the rail from its support posts, making it easier to move and less likely to puncture the car.

Offset block is a kind of bearing part between guardrail beam and post. The block itself is a energy absorbing object, which is benefit to energy absorbing, but also can reduce damage and increase the overall strength of guardrail beams.

A hexagonal hollow offset block is placed on the ground.
Galvanized hexagonal hollow offset block has superior performance of anti-corrosion and impact resistance.A thrie-beam offset block is placed on the ground.
This kind of offset block is specifically used for square posts.
Stacks of U-section offset blocks are packaged with steel strips.
U-section offset blocks are generally used with U-section posts or H-section posts.An upright C-section offset block.
C-section offset blocks are installed with C-type posts, which looks beautiful.

Channel steel is a long steel with a grooved cross-section, a carbon structural steel for construction and machinery, and a section steel with a complex cross-section and a grooved shape.

EN 10279:2000 hot rolled steel channels specification also applies to EN 10206-1:2000, EN 10163-3:2000.

Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing. Except for special requirements, it is delivered in hot rolled or forged condition; when used as die steel, it is usually delivered in hot rolled, normalized, normalized plus tempered condition.

ASTM A588 steel beam not only has high tensile and yield strengths, but also exhibits good resistance to atmospheric corrosion due to its low copper content. Given its high strength, it is lighter in weight than A36 steel without any reduction in strength. At the same time, it is the best material for outdoor applications and has an orange-brown surface. It is mostly used for bridges, buildings and construction equipment; frames for automobiles and machinery; and transmission and communication towers.

German standard H-beam DIN1025-2H is a new type of economic construction steel.

H-beam cross-sectional shape is economical and reasonable, good mechanical properties, rolling at all points on the cross-sectional extension is more uniform, internal stress is small, compared with ordinary I-beam, has the advantages of large cross-sectional modulus, light weight, metal saving, can make the building structure reduce 30-40%; and because of its legs inside and outside parallel, leg end is right angle, assembling Combined into members, it can save welding and riveting workload up to 25%.

Commonly used in large buildings (such as factory buildings, high-rise buildings, etc.), bridges, ships, lifting machinery, equipment foundations, brackets, foundation piles, etc., which require large bearing capacity and good cross-sectional stability.
