40U Steel Arch

Material:20 MnK U steel support is a kind of passive support of coal mine support, the tensile strength and the compressive strength is higher, it also has good toughness properties, the support force is higher, the support strength is higher, can used for many times, widely used in mine tunnel, especially in deep complex tunnel and loose coal seam tunnel. Application: U36 steel support is mainly used for mine tunnel, mine tunnel secondary support, as well as support through the mountain tunnel support purposes. U-shaped steel bracket Features: withstand pressure, support long time, easy to install and easy to deformation characteristics. 36U steel frame consists of a roof beams, two legs, four card cable, two bottom feet composition. Mainly used in mine tunnel, mine tunnel secondary support, as well as support through the mountain tunnel support and so on.

Model: 40u Material: 20MnK Characteristic: High initial support, strong support strength, easy installation and not easy deformation; high cross section utilization and small maintenance; the recycling rate is high, the use of timber is reduced and the environmental benefit is obvious.

The 12# mine steel arch is made of mine i beam, the material of the 12# mine steel arch is Q345B, the Application: It is mainly used in mine roadway, secondary support of mine roadway and supporting support for the tunnel. Specification: T chanel support, arch support Size: 12# Material: Q345B Characteristic: High pressure, long support time, easy to install, etc. 1. The outer edge of the i-steel shall not be more than 2.4% of the width of the legs. 2. The bending deflection of the i-steel shall not be greater than 1.0mm. 3. The degree of eccentricity of i-steel shall not be more than 2% of the width of the legs. Degree of eccentricity = b2-b1/2. 4. The bending degree of the steel shall not be greater than 3mm.

U-steel support is a kind of passive support of coal mine support, the tensile strength and the compressive strength is higher, it also has good toughness properties Material: 20Mnk Size: 25U Height: 110mm Thickness: 17mm Weight: 24.76kg/m Production: 103300T Surface treatment acid pickling Treatment Hot-rolled

The characteristics of these hangars are: Quick to install. You need a small group of workers (between 3-5 people) for the construction of the roofs. The speed in the construction is about 75-100 m2/day Cost-effective. Maximum useful space because have no pillars, nor posts, girders, etc. Each project is studied individually. This means that we adapt our buildings to the characteristics of each place (snow loads, wind loads, grain load and earthquake resistance). No structure. Our buildings have no structure so the inner space is completely free for the customer. And you don't need posts, columns, beams, girders, etc. Resistant to hard weather conditions. We manufacture buildings resistant to high speed winds (up to 300 km/hr), snow loads (up to 320 kg/m2), earthquakes, etc. Our prefabricated buildings can be changed of place without problems. High quality of our materials. Galvanised, laquered, aluzinc. Wide range of models. We have buildings from 10 up to 35 metres wide. And you can have the length that you want.
