Why Is Quality Building Material Important for Construction?

Quality building materials for construction are the single most important factor determining whether your factory or industrial facility stands strong for decades  or becomes a costly liability within years. If you’re an industrial owner in Chennai planning a new factory, warehouse, or Pre-Engineered Building (PEB), this FAQ guide will explain exactly why quality building materials for construction should be your top priority before breaking ground.

FAQ 1: Why Quality Building Materials for Construction Matter in Industrial Projects

An industrial building is subjected to much more stress compared to a residential or commercial building. The stress an industrial building is subjected to includes the following:

• Heavy machinery loads: where the floor will have to withstand the constant vibration of machines
• Large roof spans: where the roof will have to be made of steel to avoid sags over a period of time
• Severe weather conditions in Chennai: where the humidity level is very high, the salty atmosphere will corrode the steel used for construction, and the rains will further damage the structure
• Fire resistance: The material used for the construction of the building should have a particular resistance level

While a residential building will last for several decades even if constructed using average quality materials, an industrial building constructed using substandard materials will develop cracks in the structure within 3 to 5 years. This is where the owner of the factory will lose out.

The bottom line: While the cost of using average materials will be less for a building, the return on investment for using quality materials will be much higher compared to the amount saved by using substandard materials.

FAQ 2: Key Quality Building Materials for Construction of PEB Structures

The major materials used in Pre-Engineered Buildings, which are the gold standard for industrial and warehouse construction today, are:

Structural Steel (Primary Framing): Columns, Rafters, and Girders form the skeleton of your building. High-grade steel (IS 2062 Grade A or E250) with adequate yield strength is a prerequisite to ensure your building withstands wind pressure, seismic activity, and equipment loads without any deflection.

Purlins and Girts (Secondary Framing): These are the supporting structures for your roof and wall claddings. Lightweight, high-strength steel Purlins make for efficient roof construction, which is a prerequisite for large-span roofs of factories and warehouses.

Roofing and Wall Panels (Cladding): Galvalume and Galvanised Steel Sheets with a minimum 0.5mm thickness and AZ150 coating are the norm for industrial buildings. Cheap, low-grade panels have a life of only 2-3 monsoon seasons in the coastal climate of Chennai.

Fasteners and Connections: Not many people focus on this, but low-grade bolts and anchor rods are the most common reasons for joint failures. Always insist on high-tensile bolts (Grade 8.8 minimum) with torque verification.

Protective Coatings: Two-coat paint with primer and finish, using epoxy- and polyurethane-based coatings, adds an extra 20-30 years to the life of your steel structures.

FAQ 3: How does material quality affect the lifespan of my factory building?

This is one of the most important questions an industrial owner can ask. Here’s a realistic comparison:

For a factory owner, a building that lasts 40 years rather than 15 years is the difference between a one-time investment and a repeated investment. Quality materials pay for themselves many times over.

FAQ 4: Can poor building materials affect my factory’s safety certifications and compliance?

Yes significantly Buildings in industrial units in Tamil Nadu need to adhere to the following regulations:

• National Building Code (NBC) of India 2016: It has specified the minimum norms for the materials to be used for the structural soundness of the building.
• IS 800:2007: It is the Indian Standard for steel structures, which specifies the design and material requirements for the building.
• Factory Act, 1948: It has specified the need to ensure the structural soundness of the building for the safety of the workers.
• Fire NOC requirements: Fire-resistant materials need to be used for the construction of buildings, depending on the type of industry.
• Pollution Control Board inspections:  Structural soundness is also a factor during the inspections.

If the inspection finds that inferior materials have been used and the building does not conform to the structural soundness norms, the consequences could include the shutdown of your factory, issuance of penalty notices, difficulty in renewing your license, and liability in case of accidents. Always insist on the contractor providing material test certificates (MTC) before starting the construction.

FAQ 5: How to Verify Quality Building Materials for Construction Projects

Therefore, when you are looking for the best industrial construction contractors, here are the material quality checks that a factory owner should ask for while comparing the contractors:

Ask for Material Test Certificates (MTC): Every material of structural steel should have a certificate from the mills stating the grade of the material, the yield point of the material, etc. Reputed contractors like Deepika Builtech will always have this certificate ready.

Check the steel source: Contractors should be able to source the steel from certified manufacturers like SAIL, JSW, Tata, etc. Unbranded steel or rerolled steel should be strictly avoided.

Inspect the coating specifications: Ask for the paint specification from the contractors. The DFT of the paint should be a minimum of 125 microns for the main structure.

Verify the grade of bolts: Ask for a fastener specification sheet. High tensile bolts (IS 1367 Grade 8.8) should be used for all primary connections.

Look at past projects: Visit a contractor’s finished factory or warehouse and physically inspect the structure. Look for signs of rust staining, panel deformation, or joint distress, which indicate past material compromises.

FAQ 6: Is it worth spending more on premium materials for a factory building?

For industrial owners in Chennai, the answer is always: Yes. Here’s a practical look at the finances:

Imagine you are putting up a factory building of 10,000 sq. ft. Using premium grade instead of basic grade for the steel and cladding might cost you an additional ₹8-12 lakhs (5-8% extra).

But think about what you are getting in return:

• Saving ₹15-25 lakhs in repairs in the first 15 years
• Saving on insurance premiums for structurally secure buildings
• No loss in productivity because of emergency repairs
• Increased valuation in case you need to mortgage or sell the building
• Your employees’ safety is priceless, but also a major legal liability avoidance

Premium grade is not a luxury for industrial buildings. It’s the smart, risk-free option for every industrial owner.

FAQ 8: What are the signs that a building was constructed with poor-quality materials?

If you are inspecting an existing building or a contractor’s previous work, the warning signs to watch out for include:

• The presence of surface rust or rust stains on steel columns or roof purlins indicates the use of improper coating or substandard steel
• Discoloration of the roof panels or roof leaks, usually caused by the use of thin-gauge materials
• Deflection of rafters or roof purlins, indicating improper sizing of the roof structural members
• Cracked welds on connections where the column and the beam meet, indicating improper welding procedures
• Loosely fitted bolts, especially those at the base plates and the gable frames
• Buckled or loose wall panels are usually caused by the use of under-gauge materials

Any of these defects in a building less than 10 years old should be a major warning of the quality of materials used.
