Corrugated Roofing Sheets Manufacturer & Supplier in China
Sino East Steel Group manufactures corrugated roofing sheets in Tianjin, from galvanized and pre-painted steel in multiple profiles. Roofing contractors and building material traders in the Gulf source our sheets for industrial warehouses, farm buildings, boundary walls and low-rise construction, with profiles matched to local rain and wind loads.
Every shipment is manufactured to ASTM A653 / ASTM A792 / EN 10346, tested in our ISO 9001:2015 certified quality system, and delivered with a complete documentation set including the Mill Test Certificate (MTC) per EN 10204 3.1, commercial invoice, packing list, bill of lading and certificate of origin. Third-party inspection by SGS, BV or TUV can be arranged at the factory or the destination port.
Corrugated roofing sheets from our plant are roll-formed from our own galvanized and PPGI coils, which means the base metal, coating and profile are controlled in one factory instead of bought from separate traders. Profile dimensions, coating weight and paint systems are confirmed in writing before the line runs.

This integrated model removes trading markups and ensures that the specification approved in the quotation is the specification delivered.

Sheets are roll-formed from galvanized or pre-painted coil with controlled profile depth, and cut to your specified lengths to avoid on-site trimming waste. Material options include 0.35 to 0.60 mm base steel, with zinc or color coating matched to the exposure.
Every roofing sheet shipment is tracked from coil selection to the destination port, and the export team prepares the documents importers expect: bill of lading, certificate of origin, MTC with coating details and, where applicable, SASO / SABER conformity for Saudi Arabia or Dubai Municipality / ESMA support for the UAE.
How to Choose a Reliable Corrugated Roofing Sheets Supplier in China
For roofing sheets, confirm the base metal thickness, coating type and profile against the project’s wind load requirements, and ask for a physical sample to check profile depth and coating finish. Thinner sheets save money on paper but fail first in Gulf windstorms.
- Confirm the coil source - sheets are roll-formed from our own galvanized/PPGI lines
- Request coating certificates from recent roofing shipments
- Verify the profile drawing and gauge for your roof span and wind load
- Approve the RAL color and film protection in writing
- Start with one container of standard profile before a project lot
This five-point checklist has helped distributors and contractors across the GCC, Africa and Southeast Asia select the right corrugated roofing sheets partner on their first attempt, avoiding the quality and documentation problems that are common when sourcing through intermediaries.

Sino East Steel operates dedicated production lines for corrugated roofing sheets within a 65,000 m2 plant in Daqiuzhuang Industrial Park, Jinghai District, Tianjin.

Coil-to-Sheet Sourcing: One Factory for Coating and Profile
For roofing sheet, the sourcing chain is the coil: because the base coil comes from our own galvanized and PPGI lines, the zinc coating weight, paint system and profile are matched as one specification rather than assembled from separate suppliers.
- Base coils from our own galvanized/PPGI lines under long-term agreements
- Roll-forming capacity reserved for project and contract volumes
- Pre-shipment inspection by SGS, BV or TUV at the factory or destination
- Coating weight and paint thickness documented per coil in the MTC
- Quarterly price reviews for distributors and contractors
- Consolidated logistics for mixed-profile roofing orders
Roofing Sheet Quality Control, Certification and Factory Audit
Roofing sheet production runs under the ISO 9001:2015 system, with every coil tested for zinc coating weight, paint thickness and profile dimensions before the line runs. Finished sheets are checked for width, pitch, height and edge condition, and the results are summarized in the certificate that accompanies the shipment.
For large roofing programs we host factory audits and witness testing by client representatives and third parties - SGS, Bureau Veritas or TUV - before loading. Documentation can be prepared to satisfy SASO / SABER conformity for Saudi Arabia and Dubai Municipality / ESMA requirements for the UAE.
Sino East Steel Group has supplied corrugated roofing sheet to Gulf construction projects since 2008, roll-formed in our own plant from our own coils. For new buyers we provide reference lists of recent deliveries, color and profile samples, trial-order guidance and inspection arrangements.
Roofing Sheet Technical Support, Samples and After-Sales Service
Our engineers review every roofing inquiry and confirm the profile, gauge, zinc coating, paint system, color and cut length in writing before production. For coastal projects from Jeddah to Dammam we recommend Z180 or higher zinc coating and confirm the recommendation in the quotation.
- Written confirmation of profile, gauge, coating and RAL color
- MTC with coating weight and paint thickness on every shipment

Roll-Forming Profiles and Coil Selection for Roofing Sheet Orders
Corrugated roofing sheets leave our roll-forming lines in the profiles most used across the Gulf: 840, 860, 900 and YX35-125-750 trapezoidal sections, in thicknesses from 0.15 mm to 0.8 mm. The roll-forming process itself is continuous and precise - each line holds profile dimensions within the standard tolerance, so sheets from different production runs lock together cleanly on site.
Because the base coil is our own galvanized or PPGI production, the coating specification can be matched to the project location. For coastal projects from Jeddah to Dammam we recommend Z180 or higher zinc coating, and for long-life color requirements we offer PVDF or SMP paint systems in RAL colors with protective film on the painted face.
What We Confirm Before Loading
- Profile gauge check - sheet width, pitch and height verified against the profile drawing
- Coating weight test - zinc and paint thickness measured per coil, documented in the MTC
- Cut-to-length - standard 1.8 m to 12 m lengths, custom lengths for large roof spans
- Edge protection - sheets banded with edge protectors to prevent coating damage in the container
Tell us the roof span, wind load and coastal exposure when requesting a quotation - we will confirm the profile, gauge and coating before production starts.
