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.

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.
