Marine PV Aluminum Frame

6005 T5/T6 aluminum frames with a yield strength of ≥215 MPa, designed to resist deformation under extreme wind and heavy snow conditions.

Anodized to AA20, our frames deliver 25+ years of corrosion resistance, preventing oxidation in humid or acidic conditions.

Precision-engineered for 182mm cells (2278×1134 mm modules), providing a seamless fit, easy installation, and enhanced laminate waterproofing.

Precision Corners

Maintain a continuous, uniform coating, with particular attention to coverage and sealing at corners, slots, and complex sections.

Drainage-Hole Design

Position drainage holes according to module orientation to minimize prolonged saltwater retention.

Surface Texture

Keep cut edges, punched holes, and corner connections smooth and burr-free to reduce the risk of damage to sealant and backsheet.

Q1: Does a marine-grade frame mean it will never corrode?

A: No. Durability in marine environments depends on system-level factors such as coating thickness, sealing, cut edges, connection materials, maintenance, and salt-spray severity. Validation should be based on the project's environmental classification.

Q2:  Is a thicker anodic coating always better?

A: Coating thickness is only one important factor. Sealing quality, coating uniformity, dimensional fit, and connection design are equally critical and must be balanced against performance, assembly, and cost.

Q3: Can stainless-steel bolts be used directly?

A: Yes, but the risk of galvanic corrosion between aluminum and stainless steel must be assessed. Insulating washers or barrier coatings should be added where necessary.
