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 and AI-assisted input
Material recommendations and GSM ranges are starting points, not product ratings. They do not guarantee strength, waterproof performance, UV life, flame behavior, temperature performance, or suitability. The optional AI helper may misunderstand an incomplete description; review the guided answers and 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.
