The channel is a product of modern metal rolling with a profile shape similar to the letter P. It is made in two ways: by cold and hot rolling. It is used in various fields: in industry and machine tool building, machine building and construction.
Channel 16 GOST 8240-97
The hot-rolled channel of this series is produced on a special machine at high temperature. This treatment gives it high performance.
This product consists of a wall and 2 shelves. These elements are perpendicular to each other along the outer edge. Modification of shelves is carried out in the following options:
- channel 16P, in which the sides of the shelves are parallel to each other, without bias;
- 16U having an internal slope of the faces; the slope angle can be different, but not going beyond 4% -10%.
- reinforced channel, in which the sides are either parallel (16aP), or are located at a slope (16aU).
The radius R (rounding of the internal angle of the inclined faces) has a standard size of 8.5 mm. The rounding of the flange (r) is 3.5 mm for the channel of a series with a slope. For products with parallel shelves, this figure is 5.0 mm.
Product height and width
Channel 16 has a standard height and width.
- The height h indicating the distance between the shelves is 16 cm.
- The width of the flange on the outer edge, denoted by b, can be 64 mm or 68 mm.
Channel weight 16
In accordance with GOST, the channel 16 has a certain weight. This value from the actual during production may deviate by no more than 6% per product and 4.5% per batch. Actual weight is determined by weighing a single unit or the entire batch at issue to the customer.
Brand 16P:
- Channel 16 weight 1 m has 14.22 kg;
- In one ton of the product - 70.32 m.
Brand 16U:
- Channel 16 weight 1 m has 14.23 kg;
- In one ton of the product - 70.30 m.
1 meter of a channel of a series E (economic) - 14.01 kg, L (light) - 7.10 kg.
Class E and L
Economic (E) and light (L) channel channels differ in wall thickness, which they have less than the standard value. Brand 16P has the following parameters:
- economical - wall - 4.7 mm, each shelf - 8.4 mm;
- light - wall - 3.4 mm, each shelf - 5.3 mm.
The total weight and weight of 1 m of the beam, the quantity, retail and wholesale price depends on this characteristic. The characteristics also change accordingly: strength, resistance to load, stiffness. The durability of the beams, their scope, reliability and quality of construction depend on these indicators.
Main advantages
- Channel 16 has a very high strength.
- It is resistant to heavy loads, which allows the construction of buildings and structures in earthquake-prone zones.
- Relatively light weight products.
- Convenience of installation.
Application
This metal product is used to increase the stability and reliability of various designs. Due to their high strength and stiffness, the products are able to withstand large lateral loads. It is these qualities that determine the use of this material in almost all types of construction, construction of bridges, roofing runs, metal columns, supports.
It can be used as floor beams, often used for the construction of metal trusses, where the channel 16 significantly reduces the weight of the metal and removes the voltage of the main load-bearing elements. Due to its characteristics and successful configuration, the material can serve as a support for outdoor advertising, an element of viaducts or bridges. It is also used in the construction of multi-storey modern houses.
Channel 16: price
The cost of the material depends on such parameters as:
- type of product;
- steel used in its production;
- channel length;
- product weight;
- terms and method of delivery.
The cost of a wholesale lot depends on the number of products contained in one ton, and what is the balance (a beam with a smaller size is available in almost every lot).
The most expensive is the reinforced channel, which has in operation maximum strength and versatility. An important factor affecting the cost is the volume of the order. Large lots are sold at a significantly reduced price.
Average cost of products:
- channel 16 with parallel shelves 9 meters - from 29800 rubles / t; 12 meters - from 26680 rubles / t;
- products with a slope of the inner walls of the shelves of 12 meters - from 23,400 rubles / t, 9 meters - from 24,400 rubles / t.
- 1 m / n channel hot-rolled with a length of 12 m - from 615 rubles.
