AB grade may contain up to 30% B grade boards.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>A GRADE<\/strong><\/p>\n<p>The impact of a single defect is assessed by looking at the overall quality of the product.<\/p>\n<p>Completely fallen branches are not allowed on the board, but split branches may occur. The ends of the boards may be cracked. Natural colour variations are allowed, the number of live knots is not limited, the heartwood line is visible. A few flaws are acceptable if the board looks good overall.<\/p>\n<p>After installation, the visible parts of the tongue &#038; grove must be intact. Cracks hidden in the grove are tolerated. 8 cm at the end of the board are not graded (this does not apply to boards with t&#038;g at the ends).<\/p>\n<p>The surface of the boards must be smooth and presentable. A board is not suitable if its general appearance ditters significantly from the grade description.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>B GRADE<\/strong><\/p>\n<p>In general, B grade boards have a good appearance. However, individual pieces do not meet A grade requirements because the boards have one or more major defects.<\/p>\n<p>Completely broken pieces are not accepted in B grade.<br \/>\nB grade can easily be upgraded to A grade by cutting ott the defects.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>C GRADE<\/strong><\/p>\n<p>C grade consists of rejects that do not meet the parameters of B grade. The boards may be broken, have severe longitudinal cracks, many empty knotholes or other severe mechanical defects.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>IMPORTANT!<\/strong><\/p>\n<p>Boards that do not conform to the grade description cannot be cut or otherwise used. Until evaluated, the products must be stored ott the ground on a level surface and protected from UV rays. If these instructions are not followed, the boards will not be replaced.<\/p>\n<p>&#8211; All grades may contain 3% defective boards.<\/p>\n<p>&#8211; Any quality complaints must be made within 14 days of delivery.<\/p>\n<p>&#8211; When purchasing BC grade, we recommend you to inspect the products in person, as BC boards are not exchangeable and cannot be returned.<\/p>\n<p>&#8211; All thermally modified timber products that have been textured or coated with a material chosen by the customer are considered custom products. If they meet the quality description criterias for the selected grade, they are not exchangeable or returnable.<\/p>\n<p>If you have any additional questions, please contact our sales managers or email us at <a href=\"mailto:info@brolis.eu\">info@brolis.eu<\/a>.<\/p>\n<p><head><br \/>\n    <meta charset=\"UTF-8\"><br \/>\n    <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\"><br \/>\n    <title>Medienos kokyb\u0117<\/title><\/p>\n<style>\n        .gallery {\n            display: flex;\n            flex-wrap: wrap;\n            gap: 10px;\n            justify-content: flex-start;\n        }\n        .gallery div {\n            text-align: left;\n            width: 228px;\n        }\n        .gallery img {\n            width: 228px;\n            height: 542px;\n            object-fit: cover;\n        }\n        @media (max-width: 480px) {\n            .gallery {\n                justify-content: space-between;\n            }\n            .gallery div {\n                width: 42%;\n                min-width: 180px;\n            }\n            .gallery img {\n                width: 167px;\n                height: 397px;\n            }\n        }\n    <\/style>\n<p><\/head><br \/>\n<body><\/p>\n<div class=\"gallery\">\n<div>\n<img decoding=\"async\" src=\"https:\/\/www.brolistimber.eu\/wp-content\/uploads\/2025\/04\/1_-Sveikos-sakos.jpg\" alt=\"Sound knots\"><\/p>\n<p><strong>Sound knots<\/strong><br \/>A grade: Allowed, unlimited<br \/>B grade: Allowed, unlimited<\/p>\n<\/div>\n<div>\n<img decoding=\"async\" src=\"https:\/\/www.brolistimber.eu\/wp-content\/uploads\/2025\/04\/2_Saku-grupes.jpg\" alt=\"Knot cluster\"><\/p>\n<p><strong>Knot cluster<\/strong><br \/>A grade: Allowed, unlimited<br \/>B grade: Allowed, unlimited<\/p>\n<\/div>\n<div>\n<img decoding=\"async\" src=\"https:\/\/www.brolistimber.eu\/wp-content\/uploads\/2025\/04\/3_Neiskritusios-negyvos-sakos.jpg\" alt=\"Dead black knots\"><\/p>\n<p><strong>Dead black knots<\/strong><br \/>A grade: Allowed, up to 1\/10 board width<br \/>B grade: Allowed, unlimited<\/p>\n<\/div>\n<div>\n<img decoding=\"async\" src=\"https:\/\/www.brolistimber.eu\/wp-content\/uploads\/2025\/04\/4_Skilusios-sakos.jpg\" alt=\"Knot shakes\"><\/p>\n<p><strong>Knot shakes<\/strong><br \/>A grade: Allowed, up to 5 mm wide &#038;
