How To Choose Your Corrugated Sheets Profile

When embarking on a new building project, selecting the right roofing materials is important.

This guide is tailored to shed light on the various dimensions and types of metal roofing sheets.

This guide aims to demystify the width, length, and other essential attributes of these roofing components.

Understanding Roofing Sheet Dimensions

  • Width Measurement: Roofing width is gauged horizontally along the roof's base. This refers to measurements B and D in the diagram below.
  • Length Measurement: The length is assessed along the ridge, extending from the base to the apex of the roof. This refers to measurements A and C in the diagram below.
  • Importance of Accurate Measurements: Precise dimensions are vital to determine the number of sheets needed, impacting the overall cost and appearance of the roof. Always double deck any measurements.

Key Takeaway: ☀️ Accurately measuring the width and length of roofing sheets is essential for determining the quantity needed, which in turn affects cost efficiency and aesthetic appeal.

Box Profile Roofing Sheet Specifications

Box Profile roofing sheets, known for their robust design, are a staple in the roofing industry.

These sheets are not just about covering the top of a building; they are about ensuring longevity and aesthetic appeal.

  • Profiles: Common profiles include 32/1000 and 34/1000, varying slightly in height but offering the same width coverage.
  • Thickness and Color Options:
  • Applications: Thicker sheets (0.7mm) are recommended for roofing, while thinner sheets (0.5mm) are better suited for wall cladding.
  • Length Variations: Maximum lengths differ based on thickness, with 0.7mm sheets available up to 9 meters, and 0.5mm up to 7 meters.
  • Profile Comparison: While both 32/1000 and 34/1000 cover a width of 1000mm, their profile height varies, affecting the roof's overall appearance.

Key Takeaway: ☀️ Box Profile roofing sheets offer versatility in dimensions and aesthetics, making them suitable for diverse applications from roofing to cladding.

Corrugated Metal Roofing Sheet Specifications

Corrugated metal roofing sheets are celebrated for their distinctive 'wavy' design, providing not only an aesthetic appeal but also functional advantages in water drainage and maintenance.
