Lester buildings have been a vital, enduring part of the American landscape since 1947. From the early traditional post-frame days to today’s most advanced building systems, Lester’s legacy has been one of uncompromising quality and structural integrity.

The Benefits of a Lester Building
Interlocking Wall Systems
Lester Buildings have always featured time-tested interlocking framing systems that are second to none in structural integrity. Custom to every situation, Improv® suggests the most cost-effective framing system for your particular need. Improv might specify a continuous girt system (left) or flush frame system (top — typically used for insulated and lined shop buildings).
The saddled truss connection has long been the centerpiece of Lester’s wall systems. Unique in the industry, this beefy connection allows for secure fastening from both sides of the column, effectively more than doubling the strength of the connection. This design also allows for a more efficient load transfer from roof to wall.
Provides a consistent, high-quality foundation, straighter eave line and makes your building less susceptible to wind damage. Unlike others, Lester’s pre-cast footings don’t rely on variable moisture found in the soil to ensure its integrity! The factory-adhered anchor blocks provide proven, consistent uplift resistance. Note: the footings shown here are typical. However, Improv®, Lester's building design and pricing program, will properly design a footing and anchoring system needed to meet the your building’s specific design loads!

The Uni-RibTM panel is Lester’s exclusive steel roof and wall panel. It features a unique design ombination of superior steel tensile strength, an advanced corrugation pattern and optimum thickness to create the strongest 29 gage panel available today. Plus, only the highest quality exterior screw fasteners are used for strength and corrosion resistance and are backed by the company’s rigid testing program.
Stronger purlin (typically 2' x 6' versus 2' x 4' used by many others) and less deflection. Southern Yellow Pine/Douglas Fir provides better fastener holding strength. Flush design greatly reduces bird nesting, improves truss bracing and increases diaphragm strength. Uni-Lock saddle hangers eliminate purlin roll and provide a stronger connection while increasing resistance to wind uplift.
Lester’s multi-ply Uni-Frame columns have a bending capacity up to 60% greater than solid 6" X 6" posts and allow for more uniform penetration of CCA treatment. Factory-assembled, laminated columns feature a mechanically controlled nailing pattern assuring consistency; thus, overall structural integrity is improved especially if wood knots are present.
Lester’s Improv offers the flexibility of setting columns in the ground or on a concrete foundation. Lester’s Uni-Frame II system, shown here, offers the quality of a durable, steel-reinforced, poured concrete foundation.

The ratchet is mounted on the base of the truss. The plate is anchor-bolted into the concrete to secure the cover and makes for a snug fit around the base of the building.
Cross Purlins
Positioned at each coupler plate, cross purlins aid in truss alignment and integrity.
Coupler Plate
Heavy steel coupler plates are bolted to connect each section to the next.
