steel roofing sheets

2025-07-08
Corrugated sheets are primarily made from metal coils, most commonly prepainted steel coils—steel sheets coated with protective and decorative paint layers to enhance durability and corrosion resistance.
Their defining feature is the corrugated profile: a series of repeated, wave-like ridges and grooves formed through roll forming. These profiles vary in design (e.g., wave height, spacing, and shape) to serve specific functions—strengthening structural integrity, improving water runoff for roofing, or fitting diverse architectural needs like walls or industrial enclosures. The tailored corrugations balance strength, lightweight properties, and ease of installation, making them versatile for both residential and commercial construction.

The process of making prepainted corrugated steel sheets from prepainted steel coils starts with loading the coil onto an uncoiler, which unwinds it to feed the flat steel into the next stage. The flat steel then undergoes leveling to remove any curls or unevenness, ensuring a smooth surface before entering a roll forming machine, where a series of precisely shaped rollers gradually bend and press it into the desired corrugated profile through continuous rolling. After forming, the corrugated sheet is cut to the required length by a cutting device synchronized with the production speed, and finally, the finished sheets are stacked, inspected, and packaged for storage or shipment.

U channel steel

Channel steel, characterized by its distinctive U-shaped cross-section—formed by a flat web connecting two parallel flanges—stands out for its balanced structural performance in engineering applications. Typically crafted from carbon structural steel or low-alloy high-strength steel, it combines good strength, toughness, and ductility, making it a reliable choice for load-bearing roles. Its U-shaped design enhances both bending resistance and torsional stiffness, allowing it to efficiently distribute stress when used as supports in structures like building wall frames, roof trusses, or industrial machinery bases. In frame systems, such as those in warehouse shelving, workshop platforms, or bridge auxiliary structures, channel steel excels at forming stable frameworks: its flanges provide ample contact area for secure connections (via welding, bolting, or riveting), while the web reinforces the overall rigidity, reducing deformation under heavy loads. Additionally, its standardized dimensions and ease of processing—whether cutting, bending, or joining—make it adaptable to diverse project requirements, from small-scale fabrications to large-scale construction, solidifying its role as a versatile component in supports and frames across industries.

Section steel is a type of steel with specific cross-sectional shapes, widely used in construction, machinery manufacturing, bridge engineering, etc. It includes:
  • I-beams (I/H-shaped, for main structural components like beams and columns);
  • Channel steel (U-shaped, for supports and frames);
  • Angle steel (L-shaped, for connections and reinforcement);
  • T-section steel (for balanced load distribution);
  • Z-section steel (Z-shaped, for roof purlins and wall girts);
  • Special types like rail steel and sheet pile steel, for specific industrial needs.
