Lectrus equipment centers feature our innovative interlocking panel design for superior strength and performance. Walls, ceiling and roof sections all feature a unique geometry to allow adjacent panels to nest into one another. This nesting is possible due to the shape of the panels' edge, which forms a "double-J" when installed. Not only does this assure all seams are water-tight but it eliminates the need for vertical wall supports as well. Lectrus' standard interlocking panels are built from 18- to 11-gauge, G90 galvanized steel sheets. Since our interior walls are capable of supporting 400 lbs/ft (595 kg/m) and 200 ft-lbs (28 kg-m) of moment, equipment can be easily attached without additional support. Excessive snow loads are supported by a roof designed to withstand a dead load of 100 lb/ft (149 kg/m).
Our standard interlocking wall panel is 3 inches (75 mm) deep, 16 inches (400 mm) wide and lined with the specified level of fiberglass insulation. Adjacent panels are secured using #14 tek screws placed 24 inches (600 mm) on center. An 18-guage G90 steel sheet is used to form the inner wall - resulting in a very durable structure designed to last for decades. In addition, Lectrus often builds equipment centers featuring interior and/or exterior fire walls rated up to 3 hours. These structures feature the same interlocking panels as our non-fire-rated equipment centers, but also include overlapping layers of Type C gypsum board to protect the housed electrical equipment and/or nearby structures in the unlikely event of a fire.
In summary, the primary benefits of Lectrus' unique interlocking panel design include:
- Relatively low-cost as compared to site-built and fully welded prefabricated construction;
- Flexible system, ideal for constructing custom, NEMA 3R walk-in electrical enclosures;
- Weather-tight and contaminant-proof to protect your valuable electrical equipment;
- Can be designed to withstand internal or external fires, side-on pressures from explosive events of up to 4.0 psi and wind loads up to 200 mph to assure continuous operations during extreme events; and
- Easily retrofitted for future expansion and quickly repaired if damaged.
