Characteristics and Applications of 850g and 650g PVC Tent Fabric

2026-09-12

PVC‑coated polyester fabric is the mainstream enclosure material for aluminum marquees. 650g/㎡ and 850g/㎡ are two of the most widely adopted tarpaulins for wedding, event and storage marquee projects across global markets. Differences in base fabric density and coating thickness caused by varied fabric weights create obvious gaps in physical strength, weather‑resistant service life, transportation & installation cost, as well as applicable working scenarios. When doing foreign‑trade business, clarifying these distinctions for overseas buyers helps them make sensible purchasing decisions according to local climate conditions, service cycles and project budgets. It also prevents extra losses triggered by improper material selection in later operation periods.

650g/㎡ PVC tarpaulin is a medium‑weight double‑sided coated fabric manufactured with high‑strength polyester mesh as base material, covered with extruded PVC coating on both surfaces. The material features soft texture and relatively light unit weight. When rolled up, it occupies small volume, which benefits container loading and land transportation. For rental operators, it saves plenty of labor during on‑site assembly, disassembly and stacking work. It delivers qualified waterproof, anti‑UV and surface self‑cleaning performance. It can resist normal rainfall and short‑time sun exposure perfectly, meeting demands of outdoor temporary events lasting from several days to a few months. Nevertheless, limited by its overall thickness, its tear‑resistance and puncture‑resistance stay at a medium level. Under repeated pulling force from strong wind, compression weight from accumulated snow, or scratch damage from tree branches and sharp metal corners, the fabric tends to develop rips and holes more easily. This fabric is optimized for short‑term rental‑turnover projects, such as temporary wedding marquees, outdoor exhibitions and festival commercial activities, which will be disassembled and stored after events finish. It enjoys lower purchasing price and reduced logistics & labor expenditure, delivering remarkable cost‑effectiveness for frequent short‑term rental businesses. However, it is not suitable for semi‑permanent year‑round outdoor exposure, and long‑term deployment in harsh regions with high wind pressure and heavy snowfall is not advised.

850g/㎡ PVC tarpaulin is heavy‑duty industrial‑grade fabric. Its polyester base cloth is woven with higher‑density yarn, and the PVC layers on both sides are thicker. Compared with the 650g version, it achieves prominent improvement in tensile property, tear strength and puncture resistance, so it is far less vulnerable to cuts from sharp objects. Its weather resistance is greatly upgraded: it slows down UV‑caused fading under long‑time outdoor sunlight exposure, and hardly gets rigid or brittle under low‑temperature circumstances. It is capable of sustaining higher wind load and snow load, making it qualified for semi‑permanent long‑term outdoor installation. Its waterproof function and self‑cleaning capacity are further optimized; most dust and stains can be washed away simply by rainwater, lowering daily maintenance workload. It is widely applied in permanent marquees inside wedding manors, outdoor dining canopies and industrial storage tents. It is the preferred option for windy coastal zones and northern areas with heavy snow. On the downside, heavier fabric weight and larger rolled size push up sea freight and land transport cost, together with a higher unit purchasing price versus 650g material.

When making real‑world selections, heavier weight does not always mean better performance. For short‑term rental‑oriented projects, 650g fabric can fully satisfy practical requirements and hold down overall project cost. For semi‑permanent, long‑term applications or locations with severe weather, 850g fabric should be prioritized to minimize follow‑up expenses brought by fabric damage, maintenance and replacement. Apart from tarpaulin material, overall marquee safety also depends on aluminum frames with matched bearing capacity. Comprehensive evaluation combining local wind load and snow load parameters of the project site is indispensable.
