0.3mm Thickness Roofing Sheets

-- Steady & Reliable Manufacturer --

Introduction

When budget and lightness are critical factors, our 0.3mm thickness roofing sheets (or BMT equivalent) offer an economical and practical solution. This gauge is widely adopted in developing markets and for temporary structures where very low weight and ease of installation are paramount. Though thin, when combined with G550 high-tensile steel, these sheets provide surprisingly good impact resistance and structural performance.

These sheets are typically supplied as corrugated or short-span trapezoidal profiles, cut-to-length for immediate use.

Specifications

Parameter	Value/Range
Nominal Thickness	0.30mm BMT (Base Metal Thickness)
Yield Strength	G550 MPa (High Tensile Standard)
Effective Width	Typically 760mm to 914mm
Metallic Coating	GI (Z60 minimum) or GL (AZ50 minimum)
Paint System	PE (Polyester) for cost-efficiency
Standard Lengths	1.8m, 2.4m, 3.0m, or custom lengths
Profile	Corrugated, simple IBR, or shallow trapezoidal

Important Context: For roofing sheets, always refer to the Base Metal Thickness (BMT), as the total thickness including coating can be slightly higher (TCT - Total Coated Thickness).

Application

Low-Cost Housing: Economical roofing and siding solutions for residential developments.
Temporary Shelters: Quick and easy construction for site offices, storage units, and emergency shelters.
Canopies and Awnings: Lightweight coverage for small outdoor areas.
Fence Panel Infill: Non-structural perimeter fencing solutions.

Advantages

Lowest Material Cost: Provides maximum square meter coverage per ton of steel, optimizing budget.
Extreme Lightness: Minimal dead load on the structure, simplifying foundation requirements.
Ease of Transport & Installation: Can be easily handled without heavy lifting equipment.
High Tensile Strength (G550): Despite the thinness, the high-strength base steel provides necessary wind and impact resistance.

Payment & Shipping

Packaging: Sheets are tightly bundled, capped, and secured with galvanized steel straps to prevent movement and damage during sea transit.
Minimum Order: Due to production minimums, orders for 0.3mm sheets typically require a minimum quantity of 50 metric tons.
Delivery Speed: As a high-volume product, 0.3mm G550 coils are often kept in stock, leading to potentially shorter lead times (10-15 days) for standard sizes.

Frequently Asked Questions

Q: Can 0.3mm sheets handle heavy rain or wind?
A: Yes, when correctly installed using the G550 high-tensile grade, they are engineered to meet standard wind and load requirements. However, installation must follow local codes, using proper purlin spacing.

Q: How does the paint coating system ensure durability at this thickness?
A: While the base material is thin, the Z60/AZ50 metallic coating and the PE paint system still provide excellent initial protection. We recommend a quality check and repair of any scratches during installation to maximize service life.
