Steel Structure Gym Building Kit Design(80✖230)

Prefab steel structure gym building is usually made of hot-dipped galvanized H-section steel, and all components are connected together by high strength bolts.

Its fast installation, flexible design, and competitive price make it getting more and more popular in large-span warehouses or workshops, gymnasiums, shopping malls, and other public buildings. Choosing this pre-engineered 80 x 230 steel structure gym building type will save you both time and money.

Compared with other construction, steel structure gym building has advantages in use, design, construction, and comprehensive economy. The construction speed is fast, the construction pollution is small, the weight is light, the cost is low, and it can be moved at any time. These advantages of steel frame building make it a future development trend. Metal structure buildings are widely used in large-span industrial plants, warehouses, cold storages, high-rise buildings, office buildings, multi-story parking lots and residential buildings, and other construction industries.

1. Earthquake Resistance

Most of the roofs of the pre-engineered buildings are sloping roofs, so the roof structure basically adopts a triangular roof truss system made of cold-formed steel members. This steel structural system has a stronger ability to resist earthquakes and horizontal loads and is suitable for areas with a seismic intensity of more than 8 degrees.

2. Wind Resistance

The steel frame structure has lightweight, has high strength, has good overall rigidity, and has strong deformation ability. The weight of the building is only one-fifth of that of the brick-concrete structure, and it can resist a hurricane of 70 meters per second, so that life and property can be effectively protected.

3. Durability

The steel frame structure building is all composed of galvanized steel component system, which is anti-corrosion and anti-oxidation. Effectively avoid the impact of corrosion of steel plates during construction and use, and increase the service life of steel components, making it up to 50 years or more.

4. Thermal Insulation

The thermal insulation material used is mainly a sandwich panel, which has a good thermal insulation effect. The thermal resistance value of thermal insulation cotton with a thickness of about 100mm can be equivalent to a brick wall with a thickness of 1m.

5. Fast Installation

All the components of the steel structure gym building are prefabricated in the factory in advance, and only need to be connected with bolts according to the drawings after being transported to the customer’s site. There are few reprocessing links, the overall installation speed is fast, and it is less affected by the weather, environment, and seasons. For a building of about 1,000 square meters, only 8 workers and 10 working days can complete the whole process from foundation to decoration.

6. Environmental Protection & Energy Saving

Prefabricated steel structure buildings require less reprocessing of construction materials on-site, reducing environmental pollution caused by waste. Steel structure housing materials can be 100% recycled, truly green, and pollution-free. At the same time, all-steel structure buildings use high-efficiency energy-saving walls, which have good thermal insulation, heat insulation, and sound insulation effects, and can reach 50% energy saving standards.


On average, the estimated price of pre-engineered metal buildings is from $40-100 per square meter. If you have specific requirements on windproof, earthquake resistance, or anti-rust, the material cost might be higher.

In general, the wall and roof insulation material used on the metal steel building have three to four types such as rock wool, eps, glass wool, and polyurethane. The price from low to high is glass wool, eps, rock wool, and polyurethane.

The fireproof performance from high to low is rock wool, glass wool, eps, and polyurethane. The insulation performance from high to low is polyurethane, eps, rock wool, and glass wool.

Yes, you are totally able to install a steel structure building by yourself. The premise is that you can find a professional steel structure building supplier for help. Our professional technician team will save you from finding an architect. We will design and calculate the whole structure based on your given information and requirement.

At the same time, our engineer can also provide the 3D design for you. So you can actually see what your metal building construction will look like. After everything is confirmed, we will start to produce and transport all materials to your site.

For the installation, you also don’t need to worry about it. You can find an experienced contractor in your local. If your modular gym building is not very large and you want to finish it by yourself.

It’s also feasible. All our material is prefabricated; even the bolt holes are punched in advance. Everything is prepared well for assembly. We will provide you with the construction drawings for your reference. It includes detailed wall installation, roof installation, steel structure installation, etc. Anything you are not clear about, we can have a video call and guide you by phone at any time.

The design service life of the steel structure depends on the clients’ requirements. It varies from several years to dozens of years. Our professional technician team will design and calculate the whole structure based on the construction site using environment, local climate such as temperature and humidity, as well as building code.

When designing the steel structure building, our technician will make a comprehensive consideration on anti-rust, fireproof, oxidation resistance performance, which will also prolong the service life.

At the same time, if you can do regular maintenance measures such as clean the rust and repaint it after installing the steel structure building, its actual service life will also be longer.
