Product Description

41×41 Square-Edge Rib-Reinforced Serrated C Purlin | Lightweight Galvanized C Channel with Inner Toothed (Flowered) Structure for Civil Construction & Home Improvement

Product Description:

This 41×41 square-edge rib-reinforced serrated C purlin (commonly known as "flowered C channel" in the industry for its inner toothed structure) is an upgraded cold-formed steel profile optimized for civil construction and home improvement applications. Manufactured from high-strength thin-gauge steel strip via precision cold forming, it integrates two core upgrades: built-in corner reinforcing ribs and inner serrated flowered teeth.

Compared with ordinary round-corner C channels, the square-edge ribbed design greatly improves sectional rigidity and deformation resistance. The inner serrated "flowered" teeth enhance bolt clamping friction, effectively prevent fastener slipping and improve overall shear resistance of the support system.

It balances sufficient load-bearing capacity with reduced self-weight, allowing single-person handling and installation without heavy lifting equipment. The galvanized anti-rust finish delivers reliable corrosion resistance, suitable for humid indoor environments such as kitchens and bathrooms. The standardized 41×41 profile is fully compatible with mainstream strut channel accessories, enabling fast modular assembly even for non-professional installers, which effectively lowers construction difficulty and shortens project cycles.

Features:

Upgraded square-edge ribbed structure

Built-in corner reinforcement ribs enhance overall rigidity and deformation resistance, delivering higher load capacity than ordinary round-corner C-purlins at the same weight level.
Serrated "flowered" inner teeth

The inner toothed structure increases bolt clamping friction, effectively prevents fastener slipping and improves shear resistance, making the whole support system more stable and reliable.
Lightweight & labor-saving

Cold-formed thin-gauge steel maintains low dead weight; single-person handling and on-site assembly without heavy lifting equipment.
Reliable corrosion protection

Galvanized surface finish provides long-term rust resistance, suitable for humid indoor and outdoor civil construction environments.
Strong universal compatibility

Standard 41×41 size fits most common support system accessories for quick modular assembly.
Cost-effective for small projects

Ideal for water supply pipelines, heating pipes, ventilation supports, small steel structures and shelving projects in civil construction and home improvement.
