(1) according to the use environment Glulam can be divided into indoor laminated materials and outdoor laminated materials. The indoor laminated material is used in an indoor dry state, and the user's requirements can be met as long as the durability in the indoor use environment is satisfied. The outdoor laminated timber is used outdoors, and is often subjected to rain, snow, and sunlight, so it is required to have high durability. (2) according to the shape of the product Glulam can be divided into plate-shaped glulam, straight glulam and curved glulam. It is also possible to form the laminated material into a profiled section, such as an I-shaped cross-section laminated material and a box-section laminated material or a hollow section laminated material. (3) According to the bearing situation Glulam can be divided into structural glulam and non-structural glulam. The structural glulam is a load bearing member which requires the glulam to have sufficient strength and rigidity. The non-structural composite material is a non-load bearing member, which requires the appearance of the laminated material to be beautiful. (4) by use Glulam can be divided into: 1 non-structural glulam; 2 structural glulam; 3 veneer non-structural glulam; 4 veneer structure Glulam for laminated materials. Glulam does not change the structure and characteristics of wood. It is still a natural substrate like wood, but in terms of physical and mechanical properties, it is superior to solid wood in terms of tensile strength and compressive strength, and uniformity in material quality. It is also superior to solid wood. Therefore, the laminated timber can be used in place of solid wood in various corresponding fields.
HF ERW tube production
line is mainly used for continuous production of straight welded pipe, using
high frequency induction or contact welding, not only can produce round pipe,
but also can produce not more than the processing range of round pipe, square
pipe and special-shaped pipe.
