ITB began in the mid 70's using its patented Snaplock aluminum panel. The design of this panel, which dramatically reduces welding & increases speed of construction, was then...and still is...revolutionary to the industry.  ITB's proprietary Snaplock panel provides unequaled strength, and fewer welds to crack or break. Many of ITB's products are in service 20-30 years, with nearly no maintenance or repair. The Snaplock panel, which engages so securely it must be cut apart, truly provides an outstanding basis for any aluminum product.
