650gsm Fabric FAQs
What does 650gsm mean for tent fabric?
650gsm (grams per square meter) refers to the base fabric weight. This specification indicates a heavy-duty material with thick coating and dense scrim, providing superior strength, durability, and weather resistance. 650gsm is typically used for industrial, military, and heavy-duty commercial applications.
How does 650gsm compare to 500gsm or lighter fabrics?
650gsm is significantly heavier and stronger than standard fabrics (300-500gsm). It offers 50-100% higher tensile strength, greater tear resistance, and enhanced puncture protection. The heavier construction provides better UV resistance and a longer service life in demanding environments.
Is 650gsm fabric suitable for all tent applications?
While 650gsm is ideal for industrial, military, and heavy-duty applications, it may be heavier than necessary for light-duty event tents or camping applications. The added weight provides durability but may reduce portability for temporary structures.
What is the maximum width available for 650gsm fabric?
The fabric is available in widths up to 2.5 meters, allowing for efficient large-scale fabrication with reduced seam requirements. Custom widths can be manufactured for specific project needs.
Can 650gsm fabric be welded and sewn?
Yes, the fabric is suitable for both high-frequency welding (HF welding) and sewing. For sewing, use heavy-duty needles and UV-resistant thread. For welding, use appropriate temperature and pressure settings based on fabric thickness.
What is the warranty for 650gsm fabric?
The fabric comes with a 15-year warranty covering UV degradation, surface chalking, and color fading. The warranty requires proper installation and regular maintenance in accordance with manufacturer guidelines.
