How to Choose the Right GSM for PVC Coated Tarpaulin

When selecting the ideal tarpaulin for your project, GSM (grams per square meter) plays a crucial role in determining performance, durability, and suitability for different applications. At uctextile, we offer a wide range of PVC coated fabrics with various GSM options to meet the demands of industrial, commercial, and architectural uses. But how do you choose the right GSM? Let’s break it down.

What is GSM in Tarpaulin?

GSM stands for Grams per Square Meter. It refers to the weight and density of the tarpaulin fabric. A higher GSM means a heavier, thicker, and generally more durable fabric. Lower GSM fabrics are lighter, more flexible, and easier to handle.

Common GSM Ranges & Their Applications

At uctextile, our PVC tarpaulins typically range from 450gsm to 1400gsm. Here's how each range performs in real-world use:

450–550gsm – Lightweight & Flexible
Best for: Temporary covers, tent walls, agriculture shading, scaffolding wrap

Advantages: Easy to fold and transport, economical for short-term or mobile applications

650–750gsm – Medium Weight, Versatile
Best for: Truck covers, side curtains, boat covers, warehouse dividers

Advantages: Good balance of strength and flexibility, suitable for both outdoor and indoor usage

850–900gsm – Heavy Duty & Weather Resistant
Best for: Industrial curtains, architectural membranes, marine usage

Advantages: High tensile strength, UV resistance, waterproof, long-lasting in extreme conditions

1000–1400gsm – Extra Heavy Duty
Best for: Membrane structures, air domes, load-bearing covers

Advantages: Maximum durability, dimensional stability, superior flame resistance, and blockout performance

Factors to Consider When Choosing GSM

To select the right GSM for your project, consider the following:

Application Environment
Will the tarpaulin face sunlight, rain, wind, chemicals, or abrasion? Higher GSM fabrics provide better resistance.

Mobility vs. Durability
For portable or frequently moved items, a lower GSM might be more suitable. For fixed or high-load applications, go higher.

Budget
Higher GSM usually means higher cost—but also longer lifespan and fewer replacements over time.

Regulatory Requirements
Certain projects require compliance with fire-retardant (B1/B2, NFPA 701) or UV resistance standards—make sure your chosen GSM grade meets them.
