US Joist/Girder & Deck Detailing Services
• Joist :
In structural engineering, the open web steel joist (OWSJ) is a
lightweight steel truss consisting, in the standard form, of parallel chords and a
triangulated web system, proportioned to span between bearing points.
Open Web Steel Joists, K-Series, were primarily developed to provide structural
support for floors and roofs of buildings. They possess multiple advantages and
features which have resulted in their wide use and acceptance throughout the
United States and other countries.
Longspan (LH) and Deep Longspan (DLH) Steel Joists are relatively light weight
shop-manufactured steel trusses used in the direct support of floor or roof slabs
or decks between walls, beams, and main structural members.
• Girder:
Joist Girders are open web steel trusses used as primary framing members. They are
designed as simple spans supporting equally spaced concentrated loads for a floor or
roof system. These concentrated loads are considered to act at the panel points of
the Joist Girders.
These members have been standardized for depths from 20 inches (508 mm) to 120
inches (3048 mm), and spans to 120 feet (36,576 mm).
Deck:
Decks are manufactured from steel with a yield strength of up to 80 ksi, conforming
to ASTM A1008/A1008M for uncoated and painted deck and A653/A653M for
galvanized deck.
From deck is available in lengths from 6’-0” to 40’-0”. Extra charges are applied to
lengths less than 6’-0”.
Deck are available 5 type:
Roof Deck
Form Deck
Composite Deck
Diaphragm Design
