Usually use "Sheet" or "Piece" as the unit of quotation, in which the cost of rubber sponge is calculated by thickness, and the cost of fabric and processing is calculated by surface: "Rubber Sponge Cost" (Thickness, Size and Type) + "Fabric Cost" (Size and Type) + "Processing Cost" (Laminating / Coating / Embossing / Perforation).
We do not recommend the use of "Meter" or "Yard" as the unit of quotation, because the actual length of the sponge block will be longer than the standard size. Using "Meter" or "Yard" as the unit of quotation is beneficial to the factory and unfair to the customer.
Many customers feel that using "Meter" or "Yard" as the quotation unit will get continuous products, and using "Sheet" or "Piece" as the quotation unit will get single piece product, that it is incorrect. The product is continuous or single piece, and has nothing to do with the unit of quotation, only related to the packaging method, "Carton" and "Roll" are continuous products, and "Crate" is a single piece product.
Continuous Product Explain: We use glue to connect the rubber sponges and then laminate the fabric so that the neoprene fabric looks continuous. But because the rubber sponge in the middle layer has a connected by glue, can not use continuously, can only use sheet-by-sheet.
