Corrugated Steel Plate Manufacturer in China

The color coated roofing sheet is made of color-coated steel coil and processed by a Roll Forming Machine.

The main material of color paint coating is PE paint, which has the characteristics of low price, various colors and high-temperature resistance.

The corrugated colour coated sheets coating is a product obtained by subjecting a cold rolled steel sheet or a galvanized steel sheet to a surface chemical treatment (roll coating) or a composite organic coating (such as a PVC coating) and then baking and curing.

Its base steel is cold rolled sheets, hot galvanized steel sheets, and aluzinc steel sheets. The coating types can be classified into polyester, silicon modified polyester, polyvinylidene fluoride, and plastisol. The surface state of the color coated sheets can be divided into a corrugated coated sheet, a corrugated embossed sheet, and a corrugated pattern sheet.

Application

Corrugated Steel Plate Properties

Cost-effectiveness

Material Efficiency: The corrugated design uses less material while maintaining strength, reducing costs. Quick Installation: Lightweight and easy to handle, they can be installed quickly, saving on labor costs.

Strength and Durability

High Tensile Strength: Corrugated steel has a high tensile strength, making it capable of withstanding significant loads and stresses. Long Lifespan: Resistant to corrosion (especially when galvanized), these plates have a long service life.

Structural Rigidity

Increased Rigidity: The corrugated design provides enhanced structural rigidity, allowing for larger spans without support. Stability: The shape helps resist deformation under load, making it suitable for roofing and wall applications.

Versatility

Wide Range of Applications: Suitable for roofing, siding, and various structural components in commercial, industrial, and agricultural buildings. Customizable: Available in various thicknesses, colors, and finishes to meet specific design and functional requirements.

The Paints Type of Color Coated Sheet

The color coated sheets for construction are generally made of hot-dip galvanized steel sheets and hot-dip aluzinc steel sheets. They are mainly processed into corrugated sheets or sandwich sheets with polyurethane and are used for the construction of industrial and commercial buildings such as steel structure workshops, warehouses, and freezers. Roof, wall, door.

For PPGI corrugated steel roofing with a service life of 25 years and above, polyvinylidene fluoride (fluorocarbon PVDF) should be used for the paints type.

For pre-painted corrugated steel roofing with a service life of 15 years or more, the paints type should use silicon modified polyester or high weather resistant polyester.

For color corrugated steel roofing or temporary roofs with a service life of 10 years or more, polyester is used for the paints type.

How to cut corrugated galvanized steel sheet?

There are several ways to cut corrugated metal. Use a circular saw to make long, straight cuts in thicker sheets of metal. Use a pair of snips if you want to avoid power tools altogether and are working with thinner, more flexible metal or need to make curved cuts.

How to corrugate steel sheets?

To start, select the appropriate type of steel sheets, such as galvanized or cold-rolled steel. Next, cut the sheets to the desired dimensions. The corrugating process involves using a roll forming machine, which features specially designed rollers that shape the flat sheets into ridges and valleys. After corrugating, trim the edges for uniformity. Optionally, apply protective coatings like paint or galvanization to enhance durability. Finally, inspect the sheets for quality and pack them securely for delivery. This process results in strong, lightweight corrugated steel sheets suitable for various applications.

How to clean galvanized sheet metal?

Sure! Here’s a straightforward guide to fitting corrugated steel roof sheets in simple sentences:

  1. Gather tools and materials, including corrugated steel sheets, screws, and a drill.
  2. Measure the roof area to determine how many sheets you need.
  3. Cut the sheets to size using a metal shear or circular saw.
  4. Lay down a waterproof underlayment if required.
  5. Position the first sheet at one edge of the roof, allowing a slight overhang.
  6. Use a level to ensure the sheet is straight.
  7. Fasten the first sheet at the peaks with screws, about every 24 inches.
  8. Overlap the next sheet onto the first, following the manufacturer’s recommendations.
  9. Secure the new sheet in the same manner.
  10. Trim any excess overhang at the eaves if necessary.
  11. Add ridge caps at the top to cover the joints between sheets.
  12. Inspect for tight fastenings and gaps.
  13. Clean up any debris and store tools safely.

This process will help you install corrugated steel roof sheets effectively!

Can you solder galvanized sheet metal?

To fix corrugated steel roofing sheets:

Inspect the roof for damage or leaks.
Gather tools and materials, including screws and roofing sealant.
Remove damaged sheets by unscrewing them.
Clean the area where the new sheet will go.
Install replacement sheets, overlapping them and securing with screws every 24 inches.
Seal joints with roofing sealant to prevent leaks.
Tighten any loose screws on existing sheets.
Check for leaks after repairs.
Clean up any debris and store tools safely.
This will help ensure your roof is secure and waterproof!
