How to Choose Suitable Corrugated Roof Solar Mounts？

Corrugated metal roof, also known as color profiled metal sheet, is a type of profiled plate. It is made of steel sheets with color-coated surfaces, processed by rolling and cold bending into various wave shapes.

This material features light weight, high strength, rich color options and easy installation. It also delivers excellent performance in earthquake resistance, fire resistance and waterproofing. With a long service life and maintenance-free performance, it is widely used for roofing and wall enclosure of industrial plants, civil buildings, warehouses, large-span steel structures and special buildings.

At present, most corrugated metal roofs are designed as sloped roofs with a common slope of 5% and 10%. The main roof materials include single-layer profiled steel sheets and sandwich panels. The sheets are supported by purlins, which are installed on the main load-bearing structures such as portal steel frames. There are three mainstream types of corrugated metal roof structures: standing seam type, clip-lock type and through-fastened type.

These clamps are suitable for standing seam and clip-lock corrugated metal roofs. They are firmly fixed on the roof ribs with matching bolts.

The main advantage is no drilling and no damage to the original roof structure. It effectively reduces the risk of roof leakage and maintains the integrity of the metal roof, making it an ideal choice for solar mounting installation.

Trapezoidal clamps are specially designed for trapezoidal corrugated metal roofs.

During installation, waterproof tapes or sealant are applied between the clamp and roof contact surface. Then fasteners such as bolts and rivets are used to secure the clamp on the slope or top surface of trapezoidal roof ribs to achieve stable fixing for corrugated roof solar mounts.

How to choose clamps for corrugated metal roofs?

The key factors for selecting roof clamps are the cross-section wave shape of the corrugated sheet and the roof waterproofing requirements. Different roof types need matched dedicated clamps, which are essential for installing corrugated roof solar mounts.

For standing seam and clip-lock corrugated metal roofs, SPC-CK-27 are essential, with adjustable size to fit various roof profiles even after solar panels are installed. Our non-penetrating standing seam clamps require no roof drilling or piercing. They fully protect the original roof structure, deliver reliable waterproof performance, and safely fix solar panels. Made of high-grade anodized aluminum, these universal clamps feature fewer fasteners, flexible installation positions, and easy, budget-friendly mounting for residential and commercial solar projects.

For the corrugated metal roof with trapezoidal cross-section, SPC has an adjustable universal stainless steel clamp-SPC-CK-02
for trapezoidal metal roofs. Featuring flexible width and height adjustment, it fits most trapezoidal roof profiles. Complete with L brackets, self-tapping screws and EPDM gaskets, this cost-effective mounting solution enables fast, secure solar installation while preventing cold bridging.
