Compare like units
Grams per square metre and ounces per square yard both describe mass per area. One oz/yd² is approximately 33.9 g/m². A 750 g/m² cover is about 22.1 oz/yd²; 18 oz/yd² is about 610 g/m². Do not compare the numbers as though the units were the same.
Ask what the material actually is
Confirm the cover material, construction, coating, and the specification for the exact model being supplied. A heavier figure does not answer every question about how a cover performs.
Ask for supporting evidence
Request the relevant manufacturer test information, intended-use conditions, care instructions, and written warranty. Avoid treating a marketing description as a substitute for those documents.
Read the warranty separately
Confirm the covered components, period, proration, exclusions, required maintenance, and who pays associated removal or installation costs. Warranty duration is not a guaranteed service life.
Installation still matters
Use the model's handling and tensioning instructions. Temperature, wind, equipment, attachments, and the condition of the cover need to be considered for the actual installation. This article does not set a universal temperature or tension percentage.
Make the buying decision on the complete specification
Compare frame configuration, usable clearances, engineering documentation, anchoring requirements, cover specification, support, and total project scope. Fabric weight deserves a place in the comparison, not the whole decision.
Planning an installation?
