Long-grain sheets, with the face grain along the 2500 mm edge and usually written 2500 × 1250 mm, are the other format on the market. Both have the same build-up and strength; what differs is the direction in which the sheet is stiffest, which is always along the face grain. Keep that in mind for formwork spans, shelving and flooring, for cutting plans and for the look of visible parts, and ask us at quotation if you are unsure which format your project needs.\u003c\/p\u003e\n\n\u003ch2\u003eCertifications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003ePEFC Chain of Custody (FSC Mix available on request, surcharge applies)\u003c\/li\u003e\n  \u003cli\u003eCE marking per EN 13986 and UKCA\u003c\/li\u003e\n  \u003cli\u003eCARB Phase 2 and EPA TSCA Title VI\u003c\/li\u003e\n  \u003cli\u003eE1 (EN 717-1) and IKEA IOS-MAT-0181\u003c\/li\u003e\n  \u003cli\u003eF4 approval for the Japanese market\u003c\/li\u003e\n  \u003cli\u003eEnvironmental Product Declaration · REACH compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eOrdering\u003c\/h2\u003e\n\u003cp\u003ePrices shown are \u003cstrong\u003eindicative, per sheet, EXW Latvia\u003c\/strong\u003e (ex works, transport not included) and apply to the \u003cstrong\u003eminimum order of half a truck load\u003c\/strong\u003e: about 8 packs, roughly 18 m³ or 12.5 tonnes.
