Summary of Some Steel Structure Questions

These days we received several questions about steel structure buildings left by our website visitors, so today we list some of these questions in this article and will provide professional answers or suggestions for the questions. Let’s follow the editor for more details of steel structures and find out if the question you’ve asked occurs in this article.

1. How to tie down the modular structure to steel foundation?  

The connection between the structural frame and the foundation could be divided into a hinged connection and rigid connection. Generally, the hinged connection will be adapted, mainly connected by suitable anchor bolts. This connection node form should bear vertical and lateral loads at the same time. If rigid connection is used, the column foot must be large for the foundation, and the pier column must be enlarged. The buried bolts are generally distributed at the outer end of the wing plate of steel column.

2. What is a steel structure building?

Steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of beam steel, steel column, steel truss and other components made of section steel and steel plate, and adopts painted or galvanized as the anti-rust process. The components or parts are usually connected by welds, bolts or rivets. As its light weight and simple construction, it is widely used in large-scale factories, warehouses, venues, super high-rise buildings and other fields.

3. Where to buy paint for steel structure?

The paint could be purchased in local construction material market. But there are several different kinds of paints in the market before make the purchasing, the judgment should be made that which function of the paint is needed. Normally the steel structures are already painted before the delivery, and the manufacturer will know better which sort of painting will be the most suitable for the steel structure.

4. How long can a steel structure span?

Steel structure buildings are wildly used in large-span buildings. According to the safety principle, the span of the structure could reach 30 meters the most without middle pillars. And the span more than 30 meters could be achieved by adding middle pillars.

5. How much does a new steel structure cost?

We have received lots of similar questions, the unit price of a steel structure will be around $29 to $65 per square meters. Actually the exact cost of a steel structure need to be calculated based on local wind speed, rain capacity, earthquake level, also will be influenced by surface treatment, windows and doors quantity, wall panel, roof panel and etc. You can send your drawing to us if you have, or just tell us your requirements so we can provide a solution for you and quote accordingly.

6. Why we make steel structure?

The steel structure material has high strength and is easy to obtain. The steel structure building is easy to install with a flexible arrangements. The install time will be much shorter than typical concrete buildings. The steel buildings could be removed or enlarged easily because components are connected by bolts and nuts.

7. What is the most common steel structure?

The steel structures are commonly used as warehouse, workshop, poultry house as cow shed and chicken house, horse riding arena or horse stable, hangar, garage and so on. Sometimes it will be used as market or swimming pool.

8. How long can a steel structure last?

Generally, the lifetime of a steel structure will be 30-50 years, and the structure will last longer under a regular maintenance. You can check if there are any paint drop or if there are and damage of the panel at a certain time, and make the fix accordingly.
