Heavy-Duty Load-Bearing Light Steel Keel

Product features:

This heavy-duty keel stands out for its load-bearing performance and durable protective coating. Its hat-shaped cross-section distributes structural load evenly across the entire length of the keel, allowing it to support up to 3500 Newtons per linear meter, making it suitable for load-bearing partition walls in high-rise commercial buildings and industrial facilities. The polyester powder coated finish meets ASTM A653 and GB/T 11981 standards, providing superior scratch, impact, and corrosion resistance compared to plain painted or basic galvanized coatings. The precision cold-forming process ensures tight, consistent flange and web dimensions, allowing for seamless installation with standard framing hardware and wall panels. It solves critical pain points associated with standard keels, including insufficient load capacity for heavy partitions and poor durability in high-traffic industrial environments.

Product specifications:

This heavy-duty load-bearing keel has a standard length of 4000 millimeters, with a web height of 75 millimeters, flange width of 30 millimeters, and material thickness of 1.2 millimeters. Constructed from cold-formed high-strength alloy steel, it has an ultimate tensile strength of 550MPa, ensuring reliable performance for high-load structural applications. The polyester powder coated surface treatment has a coating weight of 300 grams per square meter, providing excellent resistance to scratches, impacts, and corrosion. Its hat-shaped cross-section provides optimal rigidity while minimizing material usage, and it is compatible with heavy-duty drywall screws, structural bolts, and partition wall clips for secure, long-lasting installation.

Product application:

This heavy-duty light steel keel is primarily designed for load-bearing interior partition walls in high-rise commercial buildings, warehouses, industrial factories, airport terminals, and large retail spaces. It is suitable for walls that support heavy static loads such as storage racks, heavy equipment, and multi-story mezzanine floors. Typical use cases include new construction structural framing, retrofit load-bearing partition upgrades for existing commercial buildings, and heavy-use interior spaces in manufacturing facilities. Compared to traditional concrete or wooden load-bearing walls, it offers faster installation, lower material costs, and greater design flexibility, making it a preferred choice for large-scale commercial and industrial construction projects.
