New Hampshire

Redefine your steel building experience with Allied. Our team of experts are undeterred solutionists, breaking boundaries to bring your building dreams to life.

Whether you’re building in Manchester, Nashua, Concord, Dover, Rochester or any of the neighboring cities, when building in New Hampshire, it is crucial to consider its humid continental climate, which is marked by variable weather patterns.

New Hampshire’s climate is best-known for its climatic features: rapid changes in the weather and large ranges in temperature, both daily and annually. Besides, it features significant differences between the same seasons in different years, equable distribution of precipitation, and considerable diversity from place to place. When you choose a steel building, you can have peace of mind that your property can withstand strong winds, blizzards, and snowstorms. By insulating your steel structure, it will help keep temperatures through summer as well as winter at bay.

Roof Cladding/Sheeting

Exterior metal panels attached to roof purlins, available in different gauges, colors and profiles.

Valley

Roof condition created by the intersection of the lower part of two roof planes. A hip is created by the intersection of the higher part of two roof planes.

End Wall Girt

Light gauge steel wall member that supports the wall system and horizontally spans between columns along the ends of the building.

X-Bracing

Structural members used to resist lateral forces perpendicular to rigid frames, transmitting them to the foundation. Typically, these are steel rods or angles installed in "X" configurations and found in the roof and walls.

Wall Cladding/Sheeting

Exterior metal panels attached to wall girts, available in different gauges, colors and profiles.

Rake (Gable) Trim

Metal trim piece along the rake of the roof, providing a covering at the end of the roof panel system.

Endwall Frame

Structural steel frame, consisting of columns and rafters located at the endwalls. Supports the girts and beams, and helps to transfer wind loads to the foundation.

Portal frame

Steel frame placed perpendicular to rigid frames along sidewalls for resisting lateral forces. Typically used to allow for openings in the wall.

Eave Strut

Horizontal structural member located at the eave that serves as a strut and as a juncture member for the roof and wall. These are typically cee shaped and made from cold formed steel.

Framed Opening

An opening framed by header, jamb and sill members for the placement of doors, windows, louvers or other accessory. Members consist of light gauge metal or hot rolled steel.

Purlin

Light gauge steel roof member that supports the roof system and horizonally spans between support rafters or beams.

Sidewall Girt

Light gauge steel wall member that supports the wall system and horizontally spans between columns along the sides of the building.

Rigid Frame

Primary structural steel members made from vertical columns and sloped rafters having rigid connections.

Ridge Cap

Metal trim piece along the ridge of the roof, providing a covering for the top ends of the roof panel system.

Mezzanine Joists

Structural floor system support members made from steel open web joists, steel beams or light gauge members.

Mezzanine Floor Decking

Steel decking typically supporting concrete in a floor system.

Multiple Span Columns

Gable frame, uniform depth columns, uniform or variable depth rafters, supported by columns, with ridge at center line.

Roof X-Bracing

Bracing located in the roof to transfer loads to the sturctural steel frames particularly is high wind, snow, and seismic conditions
