What are the specifications and lengths of light steel keels, and there are several sizes and models

What is the size of the light steel keel.

1. In the current decoration market, there are four main types of light steel keel wall materials, which are 50 models, 75 models, 100 models and 150 models. And the thickness of the keel is basically in, which mainly depends on the needs of your own choice.

2. When the keel is galvanized, it is either hot-dip galvanized.

Either cold galvanizing, in which cold galvanizing requires ** specific heat.

Galvanizing is lower. The components of the keel, including the main keel.

auxiliary keels, and other accessories. There are three main series: D38, D50, D60.

3. The components of the wall keel include horizontal and vertical keel, horizontal brace keel, and other accessories. There are four main series: Q50 (C50), Q75 (C75), Q100 (C100) and Q150 (C150).

4. When distinguishing the light steel keel, it is distinguished by its width, and the width determines the model of the keel. For example, if the width of the light steel keel is 50mm, then the model of this keel is the 50 keel. And the length of the light steel keel is most common in two kinds:

Three-meter-long keel and four-meter-long keel.

How to judge a high-quality light steel keel.

1. Judge according to the shape of the section.

Depending on the cross-section, the light steel keel can be divided into 4 models. Among them, the U and C keels are known as load-bearing keels and can be used as partition keels; The T and L keels are used for non-human ceilings.

2. Judge according to the thickness of the keel.

When looking at the light steel keel, we must first ensure that its thickness is above, and then look at various information of the product. At this time, it is necessary to judge the aluminum gusset by observing and touching.

of the thickness. 3. Judge according to the galvanizing process.

When making a light steel keel, it is definitely necessary to prevent it from rusting, so the surface needs to be galvanized. Here we want to see whether there is peeling off and pitting in the galvanized layer. Only by selecting qualified products can we better play the role of moisture-proof.

4. Judge according to the keel "snowflake".

Generally, the light steel keel can see a relatively clear snowflake pattern on the surface of the galvanized layer, and it also has the advantages of hard feel and small gaps.

5. Judging according to corrosion resistance.

The raw material of the light steel keel is best continuous hot-dip plate, and the galvanized layer should be very strong, and the galvanizing content on each side must also be sufficient, so as to have better anti-corrosion ability.

1 The thickness of the main bone is, 38 main bones are, 50 accessory bones, 60 auxiliary bones vertically and along the ground bones.

2. The light steel keel is divided into partition keel and ceiling keel.

3. The main specifications of the partition keel are Q50, Q75 and Q100, and the main specifications of the ceiling keel are divided into D38, D45, D50 and D60.

The common ones are 38 main bones and 75 vertical bones. Dragon's and Knauf's are all good.

Dimensions: 38 main bones, 50 accessory bones.

Model: Knauf brand.

Light steel ceiling keel.

Main keel: specification 38 12, thick; Specification 50 15, thick; Specification 60 27, thick secondary keel: specification 50 19, thick; Specification 50 20, thick; Size 60 27, thick;

Light steel partition wall keel.

Transverse keel (U-shaped): specification 50 32, thick; Specification 50 40, thick; Specification 75 32, thick; Size 75 35, thick; Size 75 40, thick; Specification 100 40, thick; Specification 150 40, thick.

Vertical keel (type C): specification, thickness; Specifications, thickness; Specifications, thickness; Specifications, thickness; Specifications, thickness; Specifications, thickness; Specifications, thickness;

Through keel (through the heart bone): specification 38 12, thick;

It's not a general problem, it's that you haven't seen it clearly, just tell him the model and size of all keels and related dimensions. For example, 38 main bones, what is his width and height?

Summary. What is the national standard specification of light steel keel The latest standard GB T11981-200860 is as follows: the thickness of the main bone is, 38 main bones are, 50 auxiliary bones, 60 auxiliary bones vertically and along the ground bones.

Light steel keel is a building material that has the effects of light weight, high strength, waterproof, shockproof, dustproof, and constant temperature. The material is widely used in hotels, terminals, stations, office buildings, interior decoration settings and other places.

What is the national standard specification of light steel keel The latest standard GB T11981-200860 is as follows: the thickness of the main bone is, 38 main bones are, 50 auxiliary bones, 60 auxiliary bones vertically and along the ground bones. Light steel keel is a building material, which has the effects of light weight, high strength, adaptability to anti-finch and water, shockproof, dust-proof, and constant temperature.

The material is widely used in hotels, waiting buildings, stations, office buildings, interior decoration settings and other places.

I want to build a house with a light steel villa on top of a brick and concrete bungalow, is it not qualified for the contractor to use a house that is all millimeters?

Theoretically, there is no problem at all with adding a light steel villa to a bungalow. However, there is one thing to note about whether local policies allow stamping. At present, in many places, it is strictly forbidden to build privately.

If the political and hidden policies at that time did not allow it, do not go to cover it, otherwise it will be forcibly demolished, and the work will be futile and the mu will be damaged, and it will not be drawn. If local policy does not restrict stamping, of course, you can happily do what you want.

The material used is 85 mm by 40 mm, and the thickness is millimeter C-shaped steel, is it not up to standard?

Galvanized C-beams are generally made of galvanized strip, and 275g m2 is equivalent to a galvanized layer thickness of 35 microns. As long as the average thickness reaches the standard, it is qualified, and there is no unified sail standard for the thickness of the zinc layer of galvanized C-shaped steel. According to the service life (maintenance isolation, unit years), environmental corrosion of the project site (unit:

grams) and other factors, choose (or calculate) to determine the thickness of the galvanized layer (grams). However, galvanized C-shaped steel is wrapped by a zinc layer, and the zinc content on the surface of the general sedan is usually 120-275g, so it will become the choice of more people.

What I want to ask is that the C-beam used by the contractor is 85 mm, 40 mm, and the thickness of the material is mm, can it meet the national minimum standard?

The error range allowed in the current international standard for C-beam is about the same. For example, the thickness of C-shaped steel is required to be 2mm, and the measured ones do not meet the requirements, and the thickness is allowed to be deviated according to the use of the square steel pipe. 1. The national standard GBT 6723-2008 general cold-formed open section steel of C-beam has specific requirements for size, shape, weight and allowable deviation.

2. There is no specific provision for the quality of the material, theoretically any material can be, and it depends on the requirements of the demand side. 3. Q195-Q235 or Q345B and other slag round to stainless steel materials, as well as hot-dip galvanizing, color coating and other surface treatments

If it is distinguished according to the use, it can be divided into partition and ceiling keel. If it is distinguished according to the cross-section, it can be divided into C, V, T and L types of keels. If it is a partition keel, its specifications are Q50, Q100 and Q75.

There is also a suspended ceiling keel, which is available in sizes D38, D50, D45 and D60. Generally, the most commonly used sizes of light steel keels are 50 mm and 60 mm. The partition wall keel is more commonly used in 75mm and 100mm.

Keel selection method.

I choose the specifications according to the application.

First of all, we need to determine the purpose of the light steel keel we purchased, and then choose the keel of the corresponding section, such as the U-type and C-type keels suitable for partition walls.

Look at the thickness. In the selection of light steel keel suitability, it is necessary to pay attention to the thickness of the product can not be lower, but also to check the product manual, carefully look at the length, thickness and other conditions, and then judge by the naked eye.

Look at the surface. Finally, look at the surface of the product, a good strong country keel, avoid snowflake packaging, the pattern is clear and hard, and the gap is small.
