Introduction
In industries ranging from construction and fabrication to furniture making and infrastructure development, the choice of MS ERW steel pipes can make or break the project’s durability and safety. Yet, with so many suppliers in the market, how do you ensure you’re buying pipes that meet the highest quality standards?
As a manufacturer of steel pipes in India with a reputation for producing 100% pure steel products — free from scrap metal — Asian Steels has compiled this 11-point quality checklist to guide you in making an informed purchase.
Whether you need MS steel square pipes, MS hollow section pipes, or MS ERW square pipes for construction, fabrication, furniture, railings, home gates, or sheds, these checks will help you avoid costly mistakes.
1. Verify the Material Purity
Not all steel pipes are created equal. Some manufacturers use scrap steel, which can compromise strength and corrosion resistance.
✅ Tip: Choose suppliers, like Asian Steels, who use 100% pure steel to ensure consistent quality and performance.
2. Check the Manufacturing Standard
Pipes should comply with IS 1239 (Part 1) and IS 4923 standards for ERW steel pipes in India. International buyers should check for ASTM or EN compliance.
✅ Tip: Ask for Mill Test Certificates (MTC) to verify compliance.
3. Inspect the Welding Quality
ERW (Electric Resistance Welded) pipes rely on strong, precise welds. Poor welding can lead to leakages or breakage.
✅ Tip: Inspect the weld seam visually and through ultrasonic testing if possible.
4. Confirm Dimensional Accuracy
Uniform outer diameter, wall thickness, and length are critical — especially for MS steel square pipes used in structural projects.
✅ Tip: Refer to Asian Steels’ Product Specifications for exact tolerances.
5. Assess Surface Finish
A smooth, scale-free finish ensures better corrosion resistance and paint adhesion.
✅ Tip: Avoid pipes with visible rust patches, pitting, or deep scratches.
6. Check for Proper End Finishing
Depending on application, pipe ends can be plain, beveled, or threaded. Proper end finishing ensures correct installation and joint strength.
7. Evaluate the Coating or Treatment
For added durability, especially in outdoor or marine environments, ensure pipes are galvanized or coated with anti-corrosion treatments.
8. Test Mechanical Properties
Yield strength, tensile strength, and elongation capacity define the pipe’s load-bearing ability.
✅ Tip: Request a test report to verify mechanical properties meet project requirements.
9. Confirm Sourcing from a Trusted Manufacturer
Buying from an established manufacturer of MS steel square pipes in India ensures accountability, consistent supply, and after-sales support.
✅ Tip: Explore Asian Steels’ facilities to understand their production capacity.
10. Review Packaging and Delivery Standards
Improper packaging can lead to dents and deformation during transport.
✅ Tip: Choose suppliers offering secure bundling and moisture protection for both domestic and global shipments.
11. Verify Application Suitability
The right pipe type depends on its application:
- Construction: MS square pipe for construction
- Fabrication: MS ERW square pipe for custom metalwork
- Furniture: Lightweight, polished pipes for aesthetics
- Railings & Gates: Durable, rust-protected pipes
Sheds: Hollow section pipes with high load capacity

Frequently Asked Questions
Q1. What is the difference between ERW and SAW pipes?
ERW pipes are made using electric resistance welding and are ideal for medium-pressure uses. SAW pipes are made using submerged arc welding and are preferred for high-pressure, large-diameter applications.
Q2. When should I use CRCA sheets?
Use CRCA sheets when surface finish and formability are critical—such as in appliances, automobiles, and electrical enclosures.
Q3. Are GP Pipes rust-resistant?
Yes. GP (Galvanized Plain) pipes are coated with zinc to provide excellent resistance to rust and corrosion.
Q4. Can I get customized sizes?
Yes. Asian Steels offers customization for volume orders based on specific dimensional and functional requirements.
Q5. Which type of steel pipe is best for water supply?
GP or GI pipes are ideal for water supply due to their corrosion-resistant zinc coating and strength in fluid transport systems.
Q6. What are the uses of SAW pipes in India?
SAW pipes are widely used in India for oil and gas transmission, city water mains, irrigation pipelines, and industrial fluid handling where high pressure and durability are critical.
