“Can I build a 60m or even 100m span warehouse with no internal columns?” This is one of the most common questions from logistics and warehousing clients.
Columns not only take up valuable storage space but also directly affect forklift traffic flow and overall operational efficiency. For projects requiring large, obstacle-free working areas, column‑free large span steel structure buildings are becoming a real necessity in overseas markets. So how do engineers actually achieve a clear span of 60 to 100 meters? The answer involves design philosophy, structural system selection, and cost control logic for large steel warehouses.

"30-meter span, no columns inside – can you do it?"
That was a question from an agricultural trader in Argentina last week. His existing warehouse has columns everywhere – forklifts struggle, trucks can't reverse in, and usable space is nearly 20% less than the floor area. Local builders either said a column-free large-span structure was impossible or quoted crazy prices.

With the continuous growth of global air transportation demand and the rapid expansion of the MRO (Maintenance, Repair, and Overhaul) market, large-span aircraft hangars have become critical infrastructure for airport operations and aviation services. These projects often involve investments of tens or even hundreds of millions of dollars.

The short answer: Aircraft hangar costs typically range from $60 to $300+ per square meter. But here's the reality: two hangars with the same floor area can differ in cost by more than three times. Why? It comes down to three key factors: structure type (steel vs. concrete vs. fabric), span size (which determines steel quantity), and the hangar door system (the biggest cost variable).

Strictly Controlling Installation Procedures to Build a Solid Foundation for Cold Storage Performance
In the field of prefabricated steel structures, the quality of cold storage projects lies not only in the stability of the steel structure itself, but also in the lasting reliability of the insulation performance of the envelope system. For professional manufacturers serving overseas markets, establishing a standardized insulation panel installation process directly determines the energy consumption, temperature stability, and service life of the cold storage facility.

Prefabricated Steel Structure Delivers Cost Efficiency for Overseas Buyers
In the field of industrial storage and bulk material handling, large-span coal sheds, as the core building form for enclosed coal storage facilities, are drawing increasing attention from overseas project owners. For clients in mining, power generation, ports, steel, and logistics industries, the question "How much does a 100m span coal shed cost?" is one of the most critical considerations during the early project evaluation stage. The answer not only affects the investment budget but also directly impacts construction timelines, operational safety, and long-term maintenance costs.
