Outstanding features

  • 11-rib steel sheet structure helps increase the load-bearing capacity and durability of the corrugated iron sheet
  • High wave and sub-wave design helps drain water quickly, effectively waterproof, increase stiffness, limit deformation during construction
  • Saving construction costs thanks to large purlin spacing helps reduce the amount of materials needed
  • Diverse in color, easy to choose, can be cut on request, suitable for many construction designs

11-rib steel sheets (also known as square 11-wave sheets) are a type of roofing material designed with 11 evenly spaced and continuous wave grooves on the surface, creating a strong and stable structure. The 11-rib steel sheets are rolled from galvanized, cold-rolled, or colored steel coils, with standard raw material widths typically being 1200mm or 914mm. After the rolling process, the finished width is reduced to 1070mm or 810mm, with each sheet having 11 evenly spaced waves. This square 11-wave design not only enhances load-bearing capacity but also optimizes rapid drainage and efficient overflow prevention, making it particularly suitable for large-scale projects with low roof slopes. 11-rib steel sheets are produced according to high-quality standards such as Japan’s JIS 3312 and America’s ASTM A365, ensuring durability and safety for users.

One of the outstanding characteristics of 11-rib steel sheets is the structure of 11 consecutive wave layers, which increases the load-bearing capacity and durability of the sheets. The high wave design combined with the secondary waves not only helps the sheets drain quickly and effectively prevent leakage but also increases stiffness and resistance to deformation during construction. 11-rib steel sheets also have good corrosion resistance thanks to the galvanized or aluminum coating, extending the product’s lifespan. With diverse colors and custom cutting capabilities, 11-rib steel sheets provide high flexibility and aesthetics for projects. Additionally, their lightweight nature makes transportation, installation, and storage easier, while also saving costs on purlins and construction. However, to ensure durability and aesthetics, users need to choose a coating layer suitable for the environment and ensure professional construction techniques.

11-rib steel sheets are widely used in various types of construction projects, from residential to industrial, including factories, warehouses, shops, restaurants, hospitals, schools, convention centers, and entertainment areas. Thanks to the high wave design and large purlin spacing, 11-rib steel sheets not only facilitate rapid drainage but also ensure sustainability against harsh weather conditions. Other outstanding features of 11-rib steel sheets include effective waterproofing and thermal insulation capabilities, the design of secondary waves to enhance stiffness, and flexibility in custom cutting based on design requirements. The product can also be combined with accessories such as self-drilling screws, gutters, and eaves to enhance aesthetics and ensure effective drainage, thereby extending the lifespan of the roof structure.
