What are weather-resistant steel structural hollow profiles? 2024-9-15

High-strength, weather-resistant hollow structural profiles (EN10210-3/ASTM A847) With hollow structural profiles, you need less steel to do the same job. EN10210-3/ASTM A847 Structural steel is commonly used in applications such as pedestrian bridges, light/telephone poles, sign brackets and building construction.

What are these?

Hollow: These profiles are not solid steel, but have a cavity in the center, making them lighter than solid profiles of the same size.

Corten Steel: They are made from weathering steel, which develops a protective rust-like patina that inhibits further corrosion, so no paint or coating is required.

High Strength: Despite being hollow, these sections are designed to be very strong and able to withstand structural loads.

Advantages of high-strength weather-resistant hollow structural profiles:

Material efficiency: The hollow design means less steel is required to achieve the same strength as a solid section, making it more cost-effective.

Lighter weight: Easier to transport and handle during construction, potentially reducing overall project costs.

Corrosion Resistant: Corten steel naturally protects itself from the elements, ensuring a long lifespan and minimal maintenance.

Common applications:

Pedestrian bridges: providing a lightweight yet strong solution.

Lamps/Poles: Street lights, poles, etc. are durable and low maintenance.

Sign Support: Withstands wind loads and environmental exposure.

Building Construction: Used on various structural elements within buildings.

Weather-resistant hollow structural profiles provide a practical and cost-effective solution where strength, corrosion resistance and reduced weight are required. Due to their durability and low maintenance requirements, they are common in outdoor applications such as bridges, utility poles, and building elements.
