Things you should know before buying the right metal sheet roof for your beautiful home and worry-free living


A metal sheet roof can add character and curb appeal to your house, but if you overlook what you need to know before choosing your metal sheet material, unexpected problems may arise later on.

Homeowners should bear in mind that a good house not only looks good but is also strong, sturdy, and long-lasting, especially those homeowners who are building or renovating a house with metal sheet roofing materials. Here are some tips to help you choose the right metal sheet roof for your beautiful home and for worry-free living.        

Metal sheet roofing materials satisfy homeowner needs for modern style due to their attractive colours, lightweight, ease of installation, and reasonable prices. The key points you need to consider when choosing a metal sheet are:     

Appropriate thicknesses for applications

Metal sheets should have thicknesses appropriate to purlin spacing. You should choose metal sheet thickness according to the type of house or and building:

  • For houses, garages, and extensions, use 0.25 mm-thick metal sheets.
  • For small and medium-sized factories, use 0.35 mm.
  • For large-sized factories or buildings, use 0.47 mm.
Paint coatings extend service life

Roof colors can enhance your house’s curb appeal. We recommend using metal sheets that conform to paint coating standards and that have superior paint adhesion and scratch resistance.

Metal sheets with high aluzinc content

TIS-certified metal sheets have aluminum-zinc coatings of at least AZ70 (70 g/sq.m.). The higher the number after AZ, the greater the aluminum-zinc content. An AZ70 coating provides four times better corrosion protection than traditional zinc coating, thus helping to extend metal sheet service life and resist rust

Trustworthy and reliable standards

It is essential to choose roofing materials that are strong and sturdy. To ensure worry-free living and safety at all times, we recommend metal sheet roofing materials with TIS certifications and international standards, which have been tested to meet the strength and impact resistance requirements.

What is good about metal sheet roofing?

  • Leak proof: Since the entire metal sheet is used without cutting, there is no leak.
  • Easy to extend: lightweight and does not add burden to the structure.
  • Bendable to any desired shape: Suitable for complex home design.
