C purlin channel are currently the most widely used type of purlins in the market. Their cross-section is C-shaped, offering excellent bending resistance and load-bearing capacity. C purlin channel can be divided into two connection methods: straight-insert type and self-locking type, making installation simple. They are lightweight, compact in structure, and suitable for roofs with a slope i<1/3, and for small to medium-span factory buildings.
C purlin channel have excellent section performance and high strength. The surface is smooth, and the dimensional accuracy is high.
C purlin channel have the advantages of simple processing and low cost, making them suitable for supporting lightweight roofs and walls.
C purlin channel are widely used in small industrial buildings, warehouses, and other constructions.
C purlin channel have diverse specifications and can be customized according to actual needs, with relatively convenient installation.
The correct placement direction of C purlin channel should consider multiple factors, including structural force, aesthetics, drainage, and dust accumulation.
Generally, the opening of C-shaped steel purlins should face upward. This arrangement can more reasonably distribute and transfer roof loads, reducing torque caused by load eccentricity.
However, when encountering door and window openings, the opening direction of the C purlin channel should be reversed, i.e., the upper window opening faces up, and the lower window sill opening faces down, to facilitate connection and construction.
For wall C purlin channel, considering the factors of water and dust accumulation, they generally face downward. But in special environments like dust-free workshops, to avoid dust accumulation, they may be chosen to face upward.
The placement direction of C purlin channel may also be affected by the position of doors and windows and needs adjustment based on specific situations.
