What is Steel Sheet and Steel Engineering?

Steel sheet and steel engineering is a set of standards and processes related to material selection, structural design, fabrication, installation, and maintenance of steel sheet roofing systems to ensure the construction project meets requirements for durability, load-bearing capacity, waterproofing, and aesthetics.

A properly engineered roofing system not only helps increase the lifespan of the construction project but also minimizes incidents arising during use.

Role of Steel Sheet and Steel Construction Engineering

Many people often only care about material cost but overlook the technical factor. However, this is the decisive factor for long-term usage efficiency.

Proper engineering will help:

• Increase steel sheet roof lifespan.
• Reduce water leakage.
• Reduce roof uplift risk during strong winds.
• Prevent sagging and structural deformation.
• Ensure aesthetics for the construction project.
• Save maintenance and repair costs.

Important Factors in Steel Sheet and Steel Engineering

1. Selecting Suitable Steel Sheet Type

This is the first but also the most important step.

Depending on each construction project, there will be a suitable steel sheet type such as:

• Electro-galvanised steel sheet.
• Galvanised steel sheet.
• Alu-zinc steel sheet.
• Color steel sheet.
• Insulated steel sheet.
• Wide steel sheet.

For areas with high humidity or near the sea, prioritize steel sheet types with good corrosion resistance to increase service life.

2. Determining Steel Sheet Thickness

Thickness directly affects load-bearing capacity.

If steel sheet is too thin:

• Easily dented.
• Causes noise.
• Low lifespan.

If too thick:

• Increased cost.
• Increased roof load.

Therefore, it is necessary to select the correct thickness according to the construction project design.

3. Purlin Spacing

This is the decisive factor for the roof's load-bearing capacity.

Purlin spacing needs to be calculated based on:

• Steel sheet type.
• Thickness.
• Roof slope.
• Wind load.
• Conditions of use.

If spaced too far apart, the roof will easily sag and shake when there is strong wind.

4. Roof Slope

A steel sheet roof with an appropriate slope will help:

• Fast water drainage.
• Limit water accumulation.
• Reduce leakage risk.

Normally, the slope will be calculated according to each type of construction project and roof length.

Standard Steel Sheet Installation Technique

Prepare Construction Surface

Before installing steel sheets, check:

• Steel frame system.
• Flatness.
• Welds.
• Load-bearing capacity.

Thorough preparation will help the installation process proceed more smoothly.

Install in Correct Order

Steel sheets must be installed from the roof edge to the roof peak.

Overlap positions must meet standards to prevent rainwater from seeping inside.

Correct Screwing Technique

This is the most common error.

Many construction units:

• Misaligned screwing.
• Over-tightening screws.
• Insufficient screwing force.

This easily tears the rubber washer and causes leakage after a period of use.

Use Compatible Accessories

A complete roof system requires:

• Ridge cap.
• Eave trim.
• Gutter.
• Storm clips.
• Anti-leakage washer.
• Specialized screws.

Do not use low-quality accessories as this will reduce the lifespan of the entire roof system.

Common Errors When Installing Steel Sheet Roofs

Many construction projects require repairs after only a few years due to errors such as:

• Incorrect purlin spacing.
• Incorrect screw placement.
• Failure to address leakage prevention.
• Incorrect steel sheet installation direction.
• Failure to clean metal shavings after screwing.
• Overlap too short.
• Failure to use storm clips.
• Cutting steel sheet with heat-generating equipment burns the coating.

These seemingly minor errors directly affect the durability of the construction project.

Steel Sheet Roof Maintenance Methods to Extend Lifespan

After commissioning, the steel sheet roof also needs periodic inspection.

Customers should:

• Clean the roof every 6–12 months.
• Check screws and rubber washers.
• Clean gutters.
• Paint and treat scratched areas.
• Replace screws or accessories when there are signs of degradation.

Proper maintenance will help the steel sheet roof maintain durability and aesthetics for many years.
