Q1: What’s the difference between SGCC and SGCH?
SGCC is a warm rolled galvanized steel with the commercial quality balance good for forming and processing, which is used for the general roofing and siding applications. SGCH has a higher strength, which makes it more suitable for applications where higher load and possibly larger span roof deck is needed.
Q2: What is the standard of SGCC / SGCH Galvanized Steel Roof Sheet?
SGCC and SGCH meet the requirements of JIS G 3302 - the Japanese Industrial Standard for Hot-dip Galvanized Steel Sheets and Strips. Popular versions are JIS G 3302:2019 & 2022.
Q3: What are the common zinc coating masses?
Typical zinc coating masses are in the range of Z12 to Z27 Zinc coating masses: Z12 Z18 Z22 and Z27 correspond to the total weight of zinc on two sides of a steel sheet 1 g.m-2 equals a layer thickness of 0.54 micron of zinc.
Q4: What are the available sizes & profiles?
SGCC / SGCH galvanized steel roofing sheets could be customized in thickness from 0.25 to 1.20 mm and width, we also supply cut to length services. The most common profiles are: corrugated, trapezoidal and ribbed, but we can make the profiles you require.
Q5: Can I use SGCC / SGCH roof sheets in outdoor and seaside environments?
Yes. With proper zinc coating selection (ex. Z22 or Z27) and good installation, SGCC / SGCH Galvanized Steel Roof Sheet can achieve good corrosion resistance for outdoor use, expectant in not too harsh sea environment.
Q6: Is it available to supply the SGCC / SGCH roofing sheet in coil or panel? Can I get Your SGCC (or SGCH) sheet in coil or in panels?
Yes the material can be provided in Galv. Coils Sheets in roll formed roofing panels based upon project requirement.
A7: How about quality control and inspection?
The products are produced in ISO 9001 quality management system and can be third party eg SGS, BV and others to check before shipment on request.
Q8: How products are packed for export?
SGCC / SGCH galvanized steel roofing tiles are packed with standard seaworthy export package, including moisture protection and material strapping to fasten the package, ensuring the safe long distance transportation.
Q9: Do we need SGCH for all roof work?
Not necessarily. SGCC is fine for regular roof sheeting and everything like that. SGCH should be used where higher strength is needed, such as in high wind-load or long-span roof.
Q10: Can you customize the specifications?
Yes you can. Customized width, thickness, zinc coating, profile design and length could be offered as per your project and market demand.
