Product overview
STRUMIN delivers steel halls built from composite (sandwich) panels for industrial, warehouse, agricultural, sports and commercial applications. Our experience covers standard and bespoke projects across domestic and international markets. Steel construction allows fast erection and cost-effective large-area solutions.

Detailed product description
Steel halls are an efficient choice for large-area investments. The steel framework enables rapid construction at competitive cost. In project development we consider the building purpose and customer requirements (number of bays, roof type, façade finish). We execute typical and tailor-made designs for small to large investments. Production in our own workshop ensures control over element quality and sizes. All realized halls use certified steel and insulation materials and are implemented in close cooperation with the investor.

Purpose of steel halls

• Warehouse halls
• Agricultural buildings
• Sports halls
• Breeding facilities
• Garage and vehicle halls
• Production and manufacturing halls
• Hangars and other specialized uses

Offer includes

• Structural design
• Manufacturing and execution
• Transportation
• On-site assembly
• Option: supply and installation of panels only or steel structure only

Main elements needed for investment valuation
Please indicate the purpose of the hall and provide the following parameters:

• H – height of the hall
• Hk – height at the ridge
• W – width of the hall
• L – length of the hall
• Ln – length of the rooflight
• Wn – width of the rooflight
• Hw – height of window openings
• Ww – width of window openings
• Hb – height of door opening (example)
• Wb – width of door opening (example)
• Hd – height of additional door opening
• Wd – width of additional door opening

STRUMIN advises
A well-optimized structural design is key to investment success. We recommend involving the hall constructor at the design stage to avoid uneconomical solutions. Typical overdesigned projects may specify 70–75 kg of steel per m2, while optimized designs target ~33–36 kg/m2. When presented with an overinvested design, we offer structural optimization to reduce cost and shorten delivery time.
