Dimensions and weight
Calculated dimensions are geometric minimums based on your inputs. Suggested stock sizes come from a limited common-size list. Actual availability, finished dimensions, tolerances, hems, seams, coatings, hardware, and moisture can change fit and weight.
Materials
Material families and GSM ranges do not guarantee strength, waterproof performance, UV life, flame behavior, temperature performance, or suitability. Use manufacturer documentation for the specific product.
Roofs and structures
Roof calculations do not design structural repairs, water management, anchoring, fall protection, or access. Damaged structures and work at height require qualified evaluation and safe procedures.
Vehicles and cargo
A tarp or weather cover is not automatically a cargo-securement system. Follow equipment ratings, carrier procedures, and all applicable laws and regulations. Do not use this site to replace a competent load-specific securement plan.
No warranty or endorsement
References to a material, standard, regulation, manufacturer, or external page do not imply endorsement or affiliation. External information can change; verify current requirements with the responsible authority.
