Technical Insight

Choosing the Right Membrane Grade (610 to 1450 gsm)

A deep dive into PVC and PVDF membrane specifications to ensure long-term performance and ROI for your structure.

The Fabric Advantage

More Than Just a Cover

The membrane is the most critical component of a tensioned structure. Selecting the correct grade is a balance between structural requirements, environmental exposure, and budget. At Champion, we offer high-tenacity polyester fabrics coated with PVC and finished with PVDF lacquers.

Understanding the difference between 610 gsm and 1450 gsm is essential for ensuring your building meets its intended service life, whether it's a temporary shelter or a permanent industrial warehouse.

🛡

UV Protection

High-grade PVDF lacquers block harmful UV rays and ensure easy cleaning.

💪

Tensile Strength

Heavier gsm grades offer superior resistance to wind and snow loads.

Grade Selection

Performance by Weight

Each grade is designed for specific applications and environmental stressors.

610 gsm PVC

Ideal for temporary shelters, small spans, and container covers where cost is the primary driver.

850 gsm PVC/PVDF

The industry standard for medium-span industrial buildings. Excellent balance of strength and translucency.

1050 gsm PVDF

Designed for large-span structures requiring higher safety factors and 20+ year lifespan.

1250 gsm Heavy Duty

Used in extreme wind zones and heavy industrial sites where high abrasion resistance is needed.

1450 gsm Maximum

The ultimate grade for permanent monumental structures and high-load engineering projects.

Insulated Options

Double-skin systems with fiberglass insulation for climate-controlled environments.

Key Benefits

Why Grade Matters

Load Resistance

Heavier fabrics handle higher pre-tension and external pressures.

Thermal Stability

Better resistance to expansion and contraction in extreme temperatures.

Flame Retardancy

All grades meet DIN 4102 B1 and NFPA 701 standards.

Self-Cleaning

PVDF surface prevents dirt accumulation and atmospheric pollution staining.
