Bamboo Fabrication manufacturer Bamboo Running Board Specification Material: 3-ply or5-ply laminated bamboo, sandwich pressed bamboo board, horizontal pressed bamboo board Finish: UV lacquer treatment Size: 500mm x 15mm x 19mm or customized size We can also provide 316 bolts and nuts as well. Bamboo vs Hardwood Bamboo board materials have three types: 鈭?Vertical-grain, created with narrow strips of bamboo glued together on-edge, giving the material a striped appearance. 鈭?Flat-grain, made with thin, flat layers of bamboo glued together, similar to the way plywood is constructed. 鈭?Stranded woven bamboo, made up of bamboo fibers bound with resin. Different types of woods are measured for their actual resilience to impact or scratching by a test known as the Janka Hardness Test, and this involves pressing a steel ball into the wood and measuring how deeply the ball dents the wood, and surprisingly, many hard woods are softer than bamboo. Among the common hardwoods woods used for flooring, furniture or parts for home furnishing, and the measurements are listed below: 鈭?Red walnut and Brazilian teak: 2,500 to 3,500 鈭?nbsp;Hard maple: 1,450 鈭?nbsp;Bamboo: 1,300 to 1,400 鈭?nbsp;Red Oak: 1,220 鈭?nbsp;Cherry: 950 鈭?nbsp;Eastern Red Cedar: 900 鈭?nbsp;Douglas Fir: 660 鈭?nbsp;Poplar: 540 鈭?nbsp;Aspen: 350 Typically, natural bamboo carries a Janka Hardness rating between 1,300 to 1,400, making it harder than most oak, and comparable to hard maple. Carbonized bamboo carries a Janka Hardness rating of around 1,000 to 1,100, which is still considerably harder than some hardwoods.Bamboo Fabrication manufacturer website:http://www.back2eco.com/bamboo-fabrication/
