Material of I-beam
The two wings are dried pine with moisture content below 13%. The knots are removed and the internal stress of the wood is eliminated by fingering with adhesives. It has the characteristics of high strength, light weight, good linearity and easy deformation. The web is three or more layers of structural plates.
The surface has the characteristics of water resistance, acid and alkali resistance.
I–beams are commonly made of structural steel but may also be formed from aluminium or other materials. A common type of I–beam is the rolled steel joist (RSJ)—sometimes incorrectly rendered as reinforced steeljoist.
An I-beam is a light beam support assembled by glueing together wooden flanges and fibreboard and plywood webs. Applications of use include the base floor-, intermediate floor and roof structures of buildings and external wall frames. I-beams are best suited in structures that require rigidity, heat insulation capacity, dimensional precision and economy. The beams are easy to work using normal carpentry tools, and holes can be made in the web plates for electrical and HVAC installations. When making alterations to the beams, however, the manufacturer’s or structural designer’s instructions must be observed. With a flanged beam, you can achieve the same load-bearing capacity with a smaller amount of material than with glued laminated timber or sawn timber, so the price is also competitive.如无特殊说明，文章均为本站原创，转载请注明出处。If there are no special instructions, the articles are original, if you want to use or reproduce, please indicate the original source www.plywoodinspection.com,If you find that our articles infringe on your copyrights and interests, please email us at firstname.lastname@example.org in time and we will delete it at the first time.
