Project Engineering Summary

Project Requirement	Q235B Steel System Response
Main material	Q235B carbon steel with hot-dip galvanized surface protection
Structural priority	Rigid steel sections for industrial roof mounting layouts
Roof requirement	Roof sheets, purlins and supporting structure must be verified
Environmental requirement	Galvanized coating specification selected according to corrosion exposure
Project delivery	Custom profiles, hole positions, component quantities and export packaging

Suitable Working Conditions

Recommended For

- ♦ Industrial metal roofs with adequate load-bearing capacity

- ♦ Factories and warehouses with strong steel purlin structures

Should You Choose Q235B Steel or AL6005-T5 Aluminum?

Choose the Q235B HDG Steel System When:

- ♦ The building has sufficient roof and purlin load capacity

- ♦ A rigid steel profile is preferred for the structural layout

- ♦ The project requires customized steel sections or hole positions

- ♦ Initial material cost is a major procurement consideration

- ♦ The galvanized coating can be specified for the installation environment

Choose the AL6005-T5 Aluminum SystemWhen:

- ♦ Reducing rooftop dead load is the main priority

- ♦ Components must be carried manually across a large roof

- ♦ Fast installation and lower handling effort are required

- ♦ The site has higher humidity or corrosion exposure

- ♦ Lower long-term coating maintenance is preferred

10-Year Warranty Solar Panel Mounting System

Product Description

The Q235B Hot-Dip Galvanized Steel Metal Roof Solar Mounting Systemis developed for industrial rooftop PV projects that prioritize structural rigidity, robust steel profiles and project-based cost control. Hot-dip galvanized Q235B components are combined with compatible roof attachments and SUS304 fasteners to support solar arrays on structurally suitable tin and metal roofs.

This system is primarily intended for factories, production facilities, warehouses and other commercial buildings with verified roof and purlin load capacity. It should not be selected solely by material price—the additional steel weight, galvanized coating requirement and roof connection design must also be evaluated.

For lightweight or corrosion-sensitive roofs, review the Anodized AL6005-T5 Aluminum Metal Roof Solar Mounting System.

Galvanizing and Installation Controls

The performance of a Q235B galvanized steel solar mounting system depends not only on the steel grade but also on the galvanized coating, fabrication process and installation details.

- ♦ Galvanized coating: Specify the required zinc coating according to humidity, salt exposure and industrial pollution.

- ♦ Cut edges and drilled holes: Any field modification should receive an approved corrosion-protection treatment.

- ♦ Water drainage: Avoid component shapes that allow water to remain inside or around the steel profile.

- ♦ Dissimilar metals: Aluminum module frames, steel profiles and stainless steel fasteners may require compatible isolation components.

- ♦ Roof penetrations: All attachment points must use a suitable sealing and waterproofing method.

- ♦ Inspection: Coating damage should be checked before packing and again after installation.

Customized Steel Mounting Components

The system can be configured using project-specific steel channels, roof brackets, module clamps and solar fasteners. Component sections, wall thicknesses, hole positions, connection plates and packaging can be adjusted according to approved structural drawings.

Pre-assembly can be arranged where practical to reduce rooftop measurements and installation steps. Final component quantities should be determined from the approved array layout rather than estimated only from the total number of modules.
