Product details

For PPGI steel coil intended for roofing sheets, describe the roll-forming profile and exposure conditions. State whether the specified thickness refers to the base metal or the finished coated product, and include the input coil width, paint system and required color.

Prepainted galvanized coil enquiries for roofing and wall profiles. Provide the profile drawing, exposure environment, color reference and forming requirements before confirming the coating system.

This specification is available for enquiry. Supply scope, dimensions and lead time must be confirmed with our team before ordering.

Color reference

Provide a color reference and agree how the finish will be approved.

Coating system

Specify the substrate, paint system and top and reverse coatings.

Profile & protection

Consider the forming process, protective film and packing together.

Typical application

Roofing & cladding

Color coated material for roofing, cladding and formed building products.

Coating test results and exposure guarantees depend on the selected paint system and order; no universal salt-spray life is implied.

Grade-specific technical data

Select the exact grade to view its composition, mechanical properties and test conditions. Grades and standards are not interchangeable; confirm the ordered edition and delivery condition. These reference tables are not a live stock list.

C	≤0.180
Mn	≤1.20
P	≤0.120
S	≤0.045
Si	≤0.50
Ti	≤0.300

Heat analysis limits; the ordered standard edition and grade take precedence. Applies only when this substrate grade is ordered; the organic coating does not define the steel strength.

Frequently asked questions

What information does a roofing coil supplier need?

Provide the roofing profile or forming requirements, input width and thickness basis, quantity, substrate and coating specification. Include paint system, color, gloss and any protective-film requirement, plus coil weight and inner diameter limits.

Can coil width be taken from the finished roof coverage width?

Provide the required input strip width separately from the finished sheet coverage. The profile and forming process affect the relationship between them. Confirm the input dimensions with the roll-forming specification before ordering.

What site information helps select a roofing coil coating?

Describe whether the roof is exposed to coastal conditions, industrial emissions or persistent moisture. Include the roof profile, drainage and any appearance requirements. Review the proposed substrate and paint system together against the project specification.

What should I specify for coils supplied to a roofing line?

Give the required input strip width, thickness basis, coil inner diameter and handling weight limit. Include the profile drawing, acceptable edge condition, coating-facing direction where relevant and quantities by colour. Keep these details consistent with the forming line and quotation.

How are minimum order and lead time confirmed?

Send your grade, size, tonnage and required delivery date. Ask for separate confirmation of stock availability, any production or processing time, and the dispatch date. Transit time depends on destination and shipment terms; the agreed quotation should state the minimum quantity and schedule.

What documents should I request?

List the required material test report, inspection document type and any third-party inspection in your enquiry. Ask which documents apply to your selected material and agree their scope before ordering. A general company certificate does not replace the material test results for the supplied heat or coil.
