Choosing the right waterproof tarpaulin is not only about rain protection, but also about durability, performance, and long-term cost efficiency. Here are 7 key factors to consider:
1️⃣ Material
The material determines the core performance of the tarpaulin:
PVC Tarpaulin
Excellent waterproof performance, high abrasion resistance, and strong weather resistance. Ideal for industrial use, transportation, and long-term outdoor applications.
PE Tarpaulin
Lightweight and economical, suitable for temporary covers and short-term use.
Canvas / Coated Canvas Tarpaulin
High strength and good tear resistance, suitable for heavy-duty applications.
The harsher the environment, the more PVC or heavy-duty canvas is recommended.
2️⃣ Weight (GSM)
GSM directly affects thickness and durability:
180–250 g/m²: temporary use, basic rain and dust protection
300–450 g/m²: general outdoor use, agriculture, and storage
500 g/m² and above: industrial and heavy-duty transportatio
For long-term outdoor use, at least 300 g/m² is recommended.
3️⃣ Waterproof Performance
A good tarpaulin must be truly waterproof:
PVC and coated tarpaulins are usually 100% waterproof
Check for waterproof coating or knife-coating/lamination processes
Ask for the water pressure resistance (mmH₂O) rating
4️⃣ UV & Weather Resistance
Essential for long-term outdoor applications:
UV stabilizers
Resistance to aging and cracking
Ability to withstand high and low temperatures
5️⃣ Workmanship & Details
Quality is reflected in the details:
Reinforced corners
Hemmed edges
Rust-resistant eyelets with reasonable spacing (e.g. every 1 meter)
Strong stitching or heat-sealed seams
6️⃣ Size & Customization
A professional manufacturer should offer:
Custom sizes, colors, and GSM
Eyelets, ropes, welding or sewing options
Logo printing
Roll materials or finished products
7️⃣ Manufacturer & Service
The supplier matters as much as the product itself:
Stable factory and export experience
Ability to provide technical data and samples
Reliable after-sales service and long-term cooperation
Professional Tip
A good waterproof tarpaulin does more than keep out rain—it must stand up to time and tough environments. Choosing the right material, weight, and a reliable manufacturer ensures long-lasting protection.
