{"product_id":"alumicolor-aluminum-calibrated-triangles","title":"Aluminum Calibrated Triangles","description":"\u003cp\u003eCalibrated triangles transform angle work from approximation into precision. Alumicolor machines these from tempered aluminum, then photo-anodizes calibrations directly into the finish, no printed markings to wear away after months of drafting. Both inch and centimeter scales run along each edge, while die-cut circles in the center provide quick radius references without reaching for a compass. The ultra-smooth finish prevents graphite transfer and surface marring, keeping technical drawings clean through repeated repositioning.\u003c\/p\u003e\n\u003cp\u003eChoose 45\/90 triangles for isometric projections and square geometry, or 30\/60\/90 versions for perspective work and hexagonal layouts. Aluminum construction means these triangles stay flat under pressure and maintain their angles through years of use, no warping like acrylic versions subjected to heat or stress. The material weight provides stability when inking or ruling precise lines, while thin profiles slip easily under templates and parallel bars. Technical illustrators and architects rely on these for the dimensional accuracy that professional drafting demands, where a quarter-degree variance compounds across a drawing into visible error.\u003c\/p\u003e","brand":"Alumicolor","offers":[{"title":"10 in. \/ 30\/60\/90","offer_id":47978840228069,"sku":"46847","price":9.46,"currency_code":"USD","in_stock":true},{"title":"10 in. \/ 45\/90","offer_id":47978840260837,"sku":"46848","price":11.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/6890\/5701\/files\/s46847.jpg?v=1761679477","url":"https:\/\/www.texasart.mom\/products\/alumicolor-aluminum-calibrated-triangles","provider":"Texas Art Supply","version":"1.0","type":"link"}
