As a specialized manufacturer of color-coated steel coils equipped with independent production lines, we are dedicated to providing high-quality coating solutions to clients worldwide.
Thanks to their exquisite craftsmanship and consistent quality, our 0.3mm color-coated coils have emerged as a star product in the international market.
Core Advantages:
Lightweight and Easy to Process: The precise 0.3mm thickness strikes an optimal balance between strength and flexibility; being lighter in weight, it facilitates easier processing, cutting, and forming, thereby effectively enhancing construction efficiency.
Our 0.3mm pre-painted steel coils have become the industry standard across Myanmar, the Philippines, and Africa. Highly valued for being economical, lightweight, and incredibly versatile, they are the go-to material for roofing and wall cladding in rapidly growing markets. 1mm Aluminium Sheet

Architecture & Infrastructure
Roofing & Wall Cladding: The 0.3mm series is a global favorite for roofing sheets and sandwich panel facings. Its lightweight profile is perfect for light industrial plants, warehouses, and prefabricated residential buildings, ensuring rapid installation and reduced structural load.
Architectural Accents: Ideal for high-precision components such as ceilings, canopies, sunshades, and window trims. This material is exceptionally easy to shape, providing a sleek, modern finish for advertising hoardings and facades.
Cleanroom Solutions: Engineered for high-hygiene environments. Our coils are used for partitions in cleanrooms and operating rooms, offering superior resistance to frequent cleaning and chemical disinfectants.
Home Appliance Industry
White Goods Casing: Precision-rolled for the appliance market. Our 0.3mm coils provide the structural skin for refrigerators, washing machines, and air conditioners. Available in high-demand finishes like Signal White, Pearl Gray, and Metallic Silver.
Small Appliances: Perfect for stamp-forming components like rice cooker housings, ovens, and water dispensers. The material’s excellent coating adhesion ensures a premium decorative look even after complex stamping and bending.
Technical Limitations (Pre-installation Checklist)
Load-Bearing Constraints: With a tensile strength of 300 to 450 MPa, our 0.3mm series is engineered specifically for lightweight cladding and decorative structures. It is not recommended for heavy-load applications or high-pressure environments with large structural spans.
Impact Sensitivity: Due to the thin profile, 0.3mm substrates have lower impact resistance compared to thicker gauges. To prevent dents or paint chipping, we recommend gentle handling during transportation and professional installation—avoiding contact with sharp or heavy objects.
Pro-Tips for Buyers
Define Your Environment: Ensure the coating type (PE, HDP, or PVDF) matches your local climate (e.g., high UV or coastal salt spray).
Verify Coating Quality: Pay close attention to the Zinc/AZ coating weight and paint adhesion tests to ensure long-term durability.
Batch Consistency: For large projects, we recommend ordering your total requirement in a single batch to ensure perfect color uniformity across all coils.
Sample Validation: Always request a physical sample or a detailed test report to verify the specifications before bulk production.
1. Why is 0.3mm the most popular thickness for international markets?
The 0.3mm thickness offers the “sweet spot” between structural integrity and cost-efficiency. It is lightweight enough to reduce transportation costs and simplify installation on-site, yet strong enough for roofing and cladding in residential and light industrial buildings. In markets like Myanmar, the Philippines, and Africa, it is the gold standard for balancing quality and budget.
2. Can 0.3mm steel coils withstand heavy rain and monsoon seasons?
Yes. While 0.3mm is a thinner gauge, its performance depends on the coating and substrate. At Bomis Steel, we ensure high-quality paint adhesion and a sufficient zinc layer (Z30-Z275). For regions with heavy rainfall or high humidity (like Southeast Asia), we recommend our HDP or PVDF coatings to provide enhanced protection against moisture and rust.
3. What is the “Yield” (Meters per Ton) for a 0.3mm steel coil?
This is a common calculation for our buyers. For a standard 0.3mm thickness and 1000mm width, 1 ton of steel coil covers approximately 420 to 450 square meters. This high yield makes it an incredibly economical choice compared to thicker specifications for large-scale surface coverage.
4. How do you prevent damage to such thin coils during shipping?
We understand that thin gauges (0.12mm–0.3mm) are more sensitive to impact. Therefore, we use Standard Seaworthy Export Packaging:
An inner layer of plastic film and moisture-proof paper.
A robust outer protective layer of galvanized iron sheet.
Strong steel strapping to ensure the coil remains stable in the container.
