Data show that about 80% of people in the fire died of inhalation of toxic gases. Therefore, the self-rescue in a fire mainly takes the approach of the body close to the ground and squats in order to avoid poisoning the smoke. As an important flooring material, the floor has a non-negligible impact in the fire environment. At this crucial moment, the flame-retardant decorative materials will play an important role in fireproofing and fire-resistance, and will win the vitality of the helpless life in the fire!
Fire-retardant flooring (GB/T24509-2009 April 1, 2010 national standard implementation): The fiberboard, particle board, plywood, etc. as the substrate, paint or impregnated paper as the decorative material, through the flame retardant treatment, to achieve a certain degree of flame retardant , Fire-retardant wood laminate flooring. Meet the B1 level flame retardant standards and smoke toxicity standards. The newly revised "Fire Protection Law of the People's Republic of China" and relevant documents of the Ministry of Public Security have also made clear provisions on fire protection requirements for public gathering places and personnel-intensive places such as restaurants, schools, and entertainment venues. The use of decoration materials must reach a certain level of flame retardancy. , otherwise fire inspection or fire safety inspection before opening shall not be passed. Therefore, the formulation of flame-retardant flooring will provide security for people in public places and gathering places.
Perforated Metal Mesh, (also named Perforated Sheet, Perforated Metal) refers to the metal sheet products with various different holes on the surface. There are many kinds of punching wire mesh products. Different shapes, different sizes of holes, can adapt to different needs.
Material: Stainless steel, low carbon steel plate, galvanized, PVC, cold rolled coil, etc.
The types: pattern perforated sheet, forming perforated plate, extra thick punching net, ultra thin punching mesh, micro porous perforated sheet metal, wire cutting punching net, Laser punching net, etc.
Shape of Hole: Rectangular hole, square hole, diamond hole, round hole, hexagonal hole, cross hole, triangle hole, long round hole, long waist hole, plum blossom hole, fish scale hole, pattern hole, five pointed hole, irregular hole, bulge hole, etc.
Use: Sound-absorbing materials for ceilings and wall of buildings; Exquisite decorative board for building staircase, balcony, environmental protection desk and chair; Machinery and equipment protection cover, grille gorgeous, food, feed, mine mill sieve, sieve screen, I-beam, stainless steel kitchen equipment, food cover, blue fruit and other kitchen utensils, and shopping malls with shelves, exhibition decoration, ventilation network for grain depot, football turf seepage water filter and so on.
Size: 1.Thickness of coil: 0.2mm-1mm; Length: 20m
2. Diameter of hole: 1.5mm-10mm
3. Thickness of plate: 0.2mm-20mm;Width*Length≤1.5m*5m
4. Diameter of hole: 0.5mm-200mm
Hole diameter:
Generally speaking, the aperture size is approximately greater than or equal to the thickness of the plate, which is in accordance with the principle of minimum pore diameter. The closer the diameter of the hole to the thickness of the sheet, the greater the difficulty of processing and the higher the processing fee.. In some raw materials, the hole size can be less than the thickness of the plate.
Pitch
The pitch is
the distance between the middle of a hole and the other one, the nearest hole
in it. The middle distance is a way to represent the interval between holes,
and the other is the rate of opening. The essential meaning of the two
representations is the same. So you just need to identify one of them.
Arrangement of holes:
(detailed picture explanation)
We can make all kinds of difficult passes and
patterns. Although special requirements for pass and pattern require a
specified processing fee, the quotation for the usual pass is quite reasonable.
(1) 60 degree staggered row
60 degree staggered row is one of the most popular choices with its natural high strength and wide
aperture ratio and attractive appearance
(2) 45 degree staggered row
Compared
with the former, the 45 degree plum blossom provides another choice for people.
(3) Straight Row
Another kind of round hole placement is straight row, straight row can also have a variety of holes and opening rate, but it is the hole in the series of the worst compressive strength.
