Q:What are the characteristics of galvanized corrugated sheet?
A:1. Anti-corrosion and durable: The galvanized layer (usually hot-dip galvanized, with a zinc layer thickness of 40-275g/m²) can effectively resist rust and extend the service life.
2. High structural strength: The corrugated design increases the bending and compression resistance of the plate and reduces the need for supporting structures.
3. Lightweight: It is lighter than concrete or ordinary steel plates, reducing building loads and transportation costs.
4. Easy to install: It can be fixed directly by screws or rivets, suitable for fast construction.
5. Economical: The cost is lower than that of color steel plates or stainless steel, but the coating thickness needs to be selected according to the environment (such as high zinc layer required in coastal areas)
Q:What are the main application scenarios of galvanized corrugated sheets?
A:Roof and wall enclosures: roof coverings for industrial plants, warehouses, agricultural greenhouses, walls and ceilings for temporary buildings (such as construction site sheds, disaster relief houses), rain shelters for stations, parking lots, etc.
Agriculture and animal husbandry: greenhouses (as frames or covering materials), livestock pens (for roofs and partitions of farms).
Transportation: sound barriers (sound barrier panels beside highways and railways), containers or carriages (side panels or roof panels of some freight containers).
Industry and infrastructure: temporary enclosures (isolation fences for construction sites and activity venues), gutter covers (lightweight covers for factories or municipal facilities).
Q:What is the difference between galvanized corrugated sheet and ordinary corrugated sheet?
A:1. Anti-corrosion treatment difference: The surface of galvanized corrugated sheet is galvanized to form a dense zinc protective layer, which can effectively block oxygen and moisture corrosion. Ordinary corrugated sheet usually uses cold-rolled steel sheet or ordinary carbon steel, without special anti-corrosion coating, and is easy to rust in a humid environment.
2. Different service life: Galvanized corrugated sheet can be used for 10-30 years in outdoor environment; through corrugated sheet usually rusts significantly in 1-5 years under the same environment, requiring frequent maintenance or replacement.
3. Different cost-effectiveness: The initial purchase cost of galvanized corrugated sheet is 30%-50% higher than that of ordinary corrugated sheet, but due to its long service life and low maintenance cost, it is more economical in the long run. Although ordinary corrugated sheet is cheap, it needs to be painted regularly to prevent rust, and the comprehensive use cost may be higher.
4. Different use environment: Galvanized corrugated sheet is particularly suitable for use in high-corrosion environments such as coastal areas and industrial areas, and is commonly seen in scenes such as factory roofs, agricultural greenhouses, and outdoor enclosures. Ordinary corrugated sheet is more suitable for temporary buildings for short-term use, or dry indoor environments.
5. Appearance difference: Galvanized corrugated sheet has a unique zinc flower texture and silver-gray appearance, and can also be color-coated to become color-coated steel sheet. Ordinary corrugated sheet is mostly the original color of steel, which will gradually oxidize and darken when exposed to air.
Q:Which is more commonly used, galvanized corrugated sheet or ordinary corrugated sheet?
A:In mainstream fields such as construction, agriculture, and industry, galvanized corrugated sheets are the absolute first choice, accounting for more than 80%; ordinary corrugated sheets are only used for temporary, short-term or special scenarios.
When choosing, you can follow the following:
Outdoor/humid environment → galvanized sheets are required;
Dry indoor/short-term use → ordinary sheets can be considered
Q:What is the difference in the surface of galvanized corrugated sheet?
A:Smooth galvanized corrugated sheet: The zinc layer is exposed, silver-gray, economical and practical.
Color-coated galvanized corrugated sheet (color steel sheet): The surface is coated with PVDF, polyester and other coatings, with various colors. Beautiful + anti-corrosion, longer life (more than 25 years).
Embossed galvanized corrugated sheet: The surface is embossed to enhance anti-slip and decorative properties.
