Product Detail

Product Classification & Details：Uniform base materials: Stainless steel (SUS304/SUS316), hot-dip galvanized steel; Q235B/Q355B carbon steel substrates.

Hex head bolts + socket head cap screws + nuts + flat & spring washers:General assembly fastening for steel brackets and aluminum accessories. Spring washers deliver enhanced anti-loosening performance to resist wind vibration in plant sites.

T-bolts + plastic wing nuts:Specially designed for photovoltaic aluminum rails. They can slide freely within the chute for positioning, suitable for installation of mid clamps, fixtures and gutter support plates.

Expansion Bolts & Chemical Anchors:Used for anchoring cement roof bases, embedded steel plates and vertical columns. Chemical anchors are applicable for positions requiring high pull-out resistance.

U-Bolts:Used together with flat iron clamps to secure circular tube columns, and wrap and lock the main beams of photovoltaic carports.

Hot-dip Galvanized Tie Rods:Diagonal bracing reinforcement for ground and carport steel brackets to improve the overall structural rigidity against wind pressure.

Self-drilling Screws:Self-drilling and self-tapping fastening for photovoltaic gutters, edge trim parts and color steel tiles, no pre-drilling required.

Applicable roof types:Universal for all scenarios including cement flat roofs, glazed tile roofs, and standing seam / angle lock color steel tile roofs.

Applicable project types:Industrial & commercial distributed PV, residential rooftop PV, ground-mounted centralized PV, photovoltaic carports, and BIPV integrated projects.

Applicable Environmental Conditions:Inland conventional factories: Hot-dip galvanized fasteners are the cost-effective preferred option;Coastal areas with salt spray and highly corrosive factories: SUS304/316 stainless steel fasteners to prevent rust completely.

Matching Supporting Products:PV accessories for aluminum alloy color steel tiles, zinc-aluminum-magnesium steel brackets, full series of PV drainage gutters.

Product Overview:This series of special fasteners and auxiliary connecting materials for photovoltaic systems adopts two anti-corrosion treatments: stainless steel and hot-dip galvanizing. They are suitable for the connection and fixation of the whole system including aluminum alloy PV accessories, zinc-aluminum-magnesium steel brackets and PV gutters.

The full range of auxiliary materials covers general bolts and washers, T-bolts dedicated to guide rails, plastic wing nuts for sliding grooves, expansion bolts and chemical anchors for cement surfaces, U-bolts for clamps, self-drilling screws for roofs, and tie rods for brackets.

All fasteners with specified specifications, lengths and anti-corrosion grades are supplied in precise matching according to on-site working conditions, construction drawings and material lists of each project. The products can effectively avoid galvanic corrosion between dissimilar metals, and the overall outdoor service life of the complete set reaches no less than 25 years.
