  The difference between LVL laminated veneer lumber and wood sawn lumber Laminated veneer lumber  (LVL) is a kind of veneer made of logs by rotary cutting or planing. After drying and gluing, the veneer is made of parallel or most of parallel billets and then bonded by hot pressing. It has the structural characteristics that solid wood sawdust does not have: high strength, high toughness, good stability, accurate specifications, and three times higher strength and toughness than solid wood sawdust. This product can be used in building formwork components, building beams, carriage boards, furniture, flooring, room decoration bamboo keel and packaging materials, etc., and has a wide range of applications. Compared with real wood sawwood, LVL has many advantages that solid wood sawwood does not possess. (1) LVL can disperse and stagger the defects such as scars and cracks of logs, thus greatly reducing the impact on strength, making it stable in quality, uniform in strength and ...

Corrosion resistance The density of  aluminum profile  is only 2.7g/cm3, which is about 1/3 of the density of steel, copper or brass (7.83g/cm3, 8.93g/cm3, respectively). Under most environmental conditions, including air, water (or saltwater), petrochemicals and many chemical systems, aluminum can show excellent corrosion resistance. Conductivity Aluminum profile is often selected because of its excellent electrical conductivity. On the basis of equal weight, the conductivity of aluminum is close to 1/2 of that of copper. Thermal conductivity The thermal conductivity of aluminum alloy is about 50-60% of copper, which is beneficial to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and automobile cylinder heads and radiators. Non-ferromagnetic Aluminum profiles are non-ferromagnetic, which is an important feature for the electrical and electronic industries. Aluminum profiles are not spontaneously combustible, which is important for appli...

1. HDPE piping is perfect for demanding applications. HDPE piping  is perfect for high-demand projects because of its durability and excellent temperature, chemical and impact resistance. For example, HDPE piping is a great choice for projects involving fire system supply lines, water, sewer and gas mains, and electrical and communications wiring and cabling. In fact, HDPE pipelines have a long history of use in the oil, mining and gas industries because they transport chemicals, wastewater, compressed gases, slurries and hazardous waste. After all, pipes are rust-resistant, corrosion-resistant, chemically and UV-resistant, immune to bacteria and less likely to leak. In addition, in addition to being durable, HDPE is surprisingly flexible and lightweight, making it easier to transport and install than other materials. This not only makes these pipes and fittings easier (and safer) to use, but it also reduces the time and labor required to install them.   2. HDPE pipe is ideal ...

Whether you're restoring a structure or planning a roof design for a new building, metal roofing is a good choice. Here are four reasons why. 1. Long life and durability According to a recent study, homeowners ranked the longevity of their roofing material as their most important consideration when choosing a roofing product. The more durable the roofing material, the longer it will last. Maintenance of the roof is another factor related to its durability. Each roof type costs a percentage of its total installed cost to maintain throughout the life of the roof.   The following are comparative percentages of maintenance costs for steep-sloped roof types as reported by building owners. Asphalt shingles - 28.5% Single-ply membrane - 19% Metal Roofing  - 3.5% Metal roofing requires a fraction of the maintenance required by other popular commercial roofing materials. Compared to the time and labor required to keep other roofs looking good, metal roofs are virtually trouble-free aft...
