Product Description

Customized Wholesale Stainless Steel Solar Panel Roof Mounting Brackets

This product is a customized wholesale stainless steel roof rack designed for PV systems, using a combination of SUS304/SUS316 stainless steel and anodized aluminum alloy, adapting to a variety of scenarios, such as metal tile roofs, color steel tiles, flat roofs and corrugated roofs. Quick installation is realized through non-penetrating clamping design (pressure ≥200N) or roof rack fixing, with a maximum load capacity of 70kg/group, and verified by 60m/s wind speed test (grade 17 typhoon) and 2.5kN/m² snow load, in line with IEC 61215 wind uncovering resistance standard. It supports 5°-40° tilt angle adjustment, is compatible with single/double-glazed modules and bifacial PV panels, and is suitable for 3-100kW systems. It combines 30+ years of service life with a lightweight design (40% less weight than galvanized steel).

Product advantages

1. Excellent corrosion resistance and life span

SUS304/SUS316 stainless steel: Containing 8% nickel (Ni) and molybdenum (Mo), it has passed 1,000 hours of salt spray test (C5-M standard), and the corrosion resistance to coastal salt spray, acid rain and industrial pollution is 3 times higher than that of galvanized steel.
Anodized aluminum alloy rail: surface oxide layer ≥15μm, anti-UV aging, and stainless steel fixture to form a double anti-rust barrier.

2. Full-scene adaptation and flexible customization

Multi-roof compatibility: Adaptable to color steel tile, Spanish tile, asphalt shingle, etc., providing replaceable fixtures (e.g. trapezoidal color steel tile hooks), no need for secondary drilling.
OEM/ODM service: support customized rail length (1-6m), inclination (5°-40°) and surface color (RAL color system), minimum order quantity 50 sets, 7 days fast delivery.

3. Extreme weather protection and high load capacity

Typhoon and snow load resistance: 60m/s wind speed test and 2.5kN/m² snow load verification, expansion joints are designed to offset -30ºC~80ºC temperature deformation.
High load-bearing structure: Maximum single-group load of 70kg, supporting double-glass modules and double-sided photovoltaic panels, with thicker-walled rails (1.5mm stainless steel tube ≈ 2.0mm galvanized tube strength).

4. Economy and Sustainability

Factory direct wholesale price: cost is 20%-30% lower than the market, no middleman premium.
100% recyclable materials: stainless steel and aluminum alloy are in line with the principles of circular economy, reducing carbon footprint.
 

 

  Installation steps

1. Roof evaluation

Check the integrity and load-bearing capacity of the tiles (≥ 1.2kN/m ²), and mark the installation position.

2. Fixture fixation

Insert the aluminum alloy fixture into the tile gap and press it to the locking position (with a "click" sound prompt).

3. Assembly of guide rails

Insert the pre installed transverse guide rail, adjust the level and lock the positioning bolt (torque 8-10N · m).

4. Component installation

Fix the photovoltaic panel with stainless steel pressure blocks, leaving a 5mm expansion gap.

5. System acceptance

Test the wind resistance pull-out force (≥ 50kg) and check the grounding resistance (≤ 4 Ω).

Application Scenario

Coastal/industrial area: SUS304 stainless steel bracket is resistant to salt spray and acid rain corrosion, adapted to high humidity and high pollution environment.
Industrial and commercial roofs: metal corrugated sheet roofs (warehouses, factories), supporting large-span arrays (100kW systems).
Agricultural facilities: greenhouse, breeding shed roof, headroom ≥ 0.5m, easy ventilation and maintenance.
Off-grid systems: RVs, ships, with Z-brackets for rapid deployment.
Residential renovation: flat-roofed apartments, villas, optimized tilt angle to enhance power generation efficiency by 10%-15%.

FAQ

 

Q1: Why are stainless steel brackets more expensive than galvanized steel? Is it worth the investment?

A: Stainless steel has a 30%-50% higher initial cost, but its maintenance-free (galvanized steel requires maintenance every 5 years), 30-year lifespan (galvanized steel is only 15-20 years), and lower whole-life cost make it an ideal choice for harsh environments or long-term projects.

Q2: Does the installation damage the roof waterproofing?

A: Non-penetrating clamps are designed to be pressure-fastened (≥200N) without the need for drilling, and are compatible with roof types such as tiles and sheet metal, in line with building warranty policies.

Q3: Can it withstand extreme weather?

A: Certified to withstand 60m/s wind speed (typhoon 17) and 2.5kN/m² snow load, the rail expansion joints can offset ±50mm temperature deformation.

Q4: Do you support small batch customization?

A: Yes. Customized rail length, inclination and color (e.g. RAL color scheme) are available, with a minimum order quantity of 50 sets and 7-day delivery.

Q5: What does the warranty cover?

A: The 10-year warranty covers material breakage, loose connections, ISO certification.
