tunnelbuilder.com - Bresciani company profile

Bresciani is a leader in the field of plastic materials and specialises in the manufacture of ventilation ducts for tunnels and mines. The latest technology and sophisticated automated equipment are used by Tunnel Wind Bresciani at its large capacity factory in Brescia, Italy to guarantee the quality of its products. The company has a worldwide sales network which can react promptly and efficiently to international market requirements.
Bresciani relies upon its lengthy experience in the field of coated fabrics to manufacture tunnel ducting that is safer and more aerodynamically efficient. In order to achieve a high standard of quality in the final product, good basic features are required of the coated fabrics used. For tunnel ventilation ducting, high mechanical tensile strength and good elasticity are required of the basic materials.
High mechanical resistance to tear is vital if accidental rupture of the ventilation duct is to be avoided, and recognition must be made of the harsh atmospheric conditions in tunnels. The fabric must survive bending, flapping, dust, moisture and fumes from diesel engines and blasting. It must also exhibit toughness and flexibility in situations where blasting may result in fly rock or spalling from the roof or sides of the tunnel.
	Bresciani ventilation ducting has a smooth internal surface to reduce load losses to a minimum, and high weldability of the fabric to guarantee perfect sealing and long life, and to allow rapid on-site modifications and repairs. For use under severe operating conditions, the company produces an antistatic-coated and flame retardant fabric which is particularly suitable if flammable gas is present.
The firm also supplies a comprehensive range of accessories. All of the coated fabrics used in the manufacture of Bresciani ventilation ducts are flame retardant and ISO 9002 approved, and are provided with quality and manufacturing certifications.
Research and development at Bresciani has developed a new exclusive tear-off joining system with internal joint covering. Fast Joint® eliminates air leaks due to blow-by, and reduces load losses to zero, with considerable power savings. This technology offers other advantages, such as faster assembly with respect to conventional systems, space-saving packaging, and easier handling. On-site tests have proved that ventilation using Fast Joint® duct is extremely safe and reliable. For safer, straighter laying, the Bresciani suspension system has a reinforced crest with eyelets every 70 cm where latest-generation labyrinth hooks are fixed. Bresciani ventilation ducting and accessories have been used by Cavet on the Bologna-Firenze high speed railway project, and by Iricav 1 on the Napoli-Roma section; by Evinos in Greece; and by Mohale Matsoku Contractors in Lesotho.
