The strongest understructure in the industry!

Interkal is AWS and CWB Certified for Welding our products.  

The Interkal understructure is designed for maximum load bearing capacity and eliminates deflection. It is constructed from the strongest and most durable materials in the industry for dependable performance you can count on for years to come. Because this understructure has few moving parts, trouble-free operation is assured with routine maintenance.  Safety features include:

•  Plastic covers at every nosebeam exposed end and/or handicap location.
•  Limit switches on non-friction automatic power systems.
•  Removable pendant control attaches to the front of the seating system for added visual safety during operation of all automatic power systems.
•  Superslide System to insure positive engagement of all vertical posts.
•  Rear closure panels to prevent debris from collecting under units.
•  Aisles and rails in compliance with applicable code requirements.

Interkal supports the NFPA-102 mandate for annual bleacher inspection and maintenance.
We strongly recommend a routine maintenance program.
