Product Description
Galvalume steel corrugated roof sheet has designs of wavy, trapezoidal designs, ribbed galvanized roof panels, etc. It can be used as a single-layer board, covering an existing roof, or a steel sandwich panel. Galvalume sheet itself is more cost-effective than traditional roofing materials. In addition, it is light in weight and easy and quick to install. In addition, it is durable and recyclable and requires less maintenance. All these factors make galvalume steel corrugated roof sheet an economical choice. It has a bright and smooth surface. The corrugated design is also excellent from the outside. In addition, it has good adhesion, so you can paint it in different colors. Having a galvalume steel roof makes it easy to achieve aesthetic purposes.
Superior Corrosion Resistance
The aluminum layer makes the aluminized zinc steel have excellent corrosion resistance. When the zinc wears, the aluminum will form a dense aluminum oxide layer, preventing the corrosion-resistant substance from further corroding the interior. Therefore, the corrosion resistance of GL plate is 3 times that of galvanized plate. Under the same circumstances, the service life of GL roof panels is 2-6 times that of GI roof panels.
High Thermal Reflectivity
Its reflection coefficient is twice that of galvanized metal roof panels, which can reduce the indoor temperature in summer and reduce the power consumption of air conditioning. This feature makes it ideal for hot climates.
High Temperature Resistance
GL roofing sheet has good heat resistance and can withstand high temperatures above 300 degrees. Therefore, it can be used for a long time at high temperature.
Smooth Surface, Uniform Appearance
The aluminized zinc roof panels are smooth, silvery white with uniform sequins. It looks beautiful and can be used directly. Therefore, it is widely used for commercial and residential purposes.
Good Formability And Adhesion
The adhesion between the GL coating and the paint is good and easy to paint. In addition, it also has excellent formability. That is, punching, cutting, and the like are easy.

FAQ
Q1: What types of steel products does your company primarily manufacture and supply?
A: We are a direct manufacturer specializing in carbon steel, hot-dip galvanized steel, PPGI (pre-painted galvanized iron), and stainless steel (grades 201, 304, and 316) in the form of sheets, coils, pipes, and various structural profiles, along with complementary steel structural components. Our products serve a wide range of industries, including infrastructure, photovoltaics, machinery manufacturing, chemicals, and new energy.
Q2: Do you support customization regarding material grades, thicknesses, and dimensions?
A: Customization is available across our entire product range. For carbon steel, galvanized steel, and stainless steel, we can adjust thickness, width, and cut-to-length dimensions according to GB, ASTM, or EN standards. Various profiles can be cut and bent based on customer drawings, and special steel grades can be produced through customized scheduling.
Q3: What is the difference between galvanized steel and color-coated (PPGI) steel, and how should I choose for my project?
A: Hot-dip galvanized steel features a pure zinc anti-rust layer; it is cost-effective and impact-resistant, making it ideal for mounting brackets, guardrails, and load-bearing factory structures (and it can be painted over). PPGI color-coated steel uses a galvanized base, offering both rust protection and aesthetic appeal with a wide range of colors; it is commonly used for factory roofing, wall cladding, and energy storage equipment casings. We recommend thicker galvanized coatings for projects in rainy coastal areas, color-coated sheets for outdoor projects requiring visual appeal, and weather-resistant fluorocarbon (PVDF) coatings for high-temperature desert environments.
Q4: Does the factory keep stock on hand, and what is the minimum order quantity (MOQ)?
A: We operate our own standardized, zoned warehouse with a capacity of over 10,000 tons, maintaining ample stock of carbon steel, galvanized steel, and stainless steel. The MOQ for standard specifications is 1 ton, though we also accept sample orders as small as a few dozen kilograms. There is no upper limit for large-scale projects, and we support mixed-load shipments combining different steel products in a single container.
Q5: What are the lead times for stock items versus customized products?
A: Standard stock items take 3–7 days for processing, packaging, and container loading. Simple cutting and bending orders take 7–10 days. Orders requiring mold creation or special steel customization take 15–30 days; exact delivery dates are confirmed based on the customer's specific order specifications.
