0.14mm SGCH Full Hard Galvanized Corrugated Roof Panel with 1050mm Effective Width and 30–275g/m² Zinc Coating

1.Product Overview

This galvanized corrugated roof panel is designed for lightweight roofing and wall cladding applications in industrial buildings, warehouses, workshops, mobile houses, and other steel structure projects. The corrugated profile improves panel stiffness compared with flat sheet, while the galvanized coating helps protect the steel surface during storage, transport, and outdoor use.

For this specification, 0.14 mm thickness and 1050 mm effective width are suitable for lightweight enclosure systems where panel weight, installation speed, and coverage efficiency are important. SGCH full hard substrate is commonly used when better profile retention is needed after corrugation forming.

2.Technical Solution

Product performance is based on the combination of galvanized coating, corrugated profile, and full hard substrate. The zinc layer acts as both barrier protection and sacrificial protection, helping reduce corrosion on the steel surface in normal service conditions.

The 76 mm wave width and 17 mm wave height improve drainage and sheet rigidity. For thin roofing sheets, profile shape and support spacing are critical. Using SGCH full hard material helps the panel maintain its formed shape during handling, fixing, and service.

7.How to Choose

• For lightweight roofing with controlled support spacing, 0.14 mm can be used as an economical option.
• For higher wind load or longer support spacing, a thicker sheet is usually preferred.
• For more humid or more exposed outdoor environments, higher zinc coating levels are commonly selected.
• For project installation efficiency, effective width and cut length should be confirmed before production.
• For better profile rigidity in thin-gauge roofing sheets, full hard grades such as SGCH are often preferred.

8.FAQ

Q1: Is 0.14 mm suitable for roofing sheets?
Yes, it can be used in lightweight roofing systems, but purlin spacing, wind load, and project design conditions should be checked carefully.

Q2: What does effective width mean?
Effective width is the actual installed cover width after the sheet profile and side overlap are taken into account.

Q3: Why is SGCH full hard used for corrugated roofing panels?
Because full hard material helps maintain the corrugated profile shape and improves rigidity after roll forming.

Q4: Can the panel length be customized?
Yes, corrugated roofing sheets are commonly cut to project-based lengths according to installation requirements.

Q5: What zinc coating should be used for outdoor building applications?
The suitable coating depends on the service environment, but higher coating levels are generally preferred when stronger corrosion resistance is required.
