Clear spans depend on truss spacing and floor loading requirements, but the maximum clear spans achievable (distance between bearings) with OPEN JOIST are: See similar questions...

open-web floor truss assembled through a unique process of finger joinery and waterproof structural adhesive instead of metal plates. See similar questions...

Maximum Allowable Spans for #2 Douglas Fir-Larch1,2,3City of Medford and Jackson County Building Departments Roof, no ceiling; Low slope rafters=L/240; High slope rafters=L/180; Floors=L/360; Ceilings=L/240 (Drywall). See similar questions...

OPEN JOIST is an engineered floor truss that takes advantage of the structural power of the triangle and the forces of compression and tension working together to create superior strength. See similar questions...

OPEN JOIST uses phenol resorcinol adhesive. This structural adhesive is the standard of the engineered wood products industry (also used by I-Joist and Glu-Lam manufacturers) and has been in use since the late 1940's. It is safe to say that the wood fiber in an OPEN JOIST floor truss would disintegrate from age before this glue would break down. See similar questions...

Generally, Railspan® units are limited to 80 feet, rarely as much as 87 feet. (Spans may be adjoined end-to-end). Longer spans will require Newspan® design. See similar questions...

The term "clear-span" refers to CoverShots' clear-span truss design. The unit is designed with modified tri-chord tubular steel truss, supported by either a modified A-frame or inverted T-post end pieces. The clear span design allows for 100% usable space beneath the canopy. See similar questions...

Yes. OPEN JOIST has been approved for use by BOCA, ICBO and SBCCI code agencies. National Evaluation Service, Inc. has issued National Evaluation Report Number NER-502 for the product. See similar questions...

No. The superior strength and highly competitive cost make it a natural choice for many commercial construction projects. The product's strength/cost ratio makes it an attractive floor-framing system for almost any building project. an open-web floor truss, OPEN JOIST normally issues floor-system designs using the standard floor truss deflection criteria of L/360, because open-web floor joists allow the use of "strongback" bracing (see installation details).

engineered floor system layout is supplied with every shipment, along with general framing details and information for framers. Generally, a builder only has to keep in mind a few things when framing with OPEN JOIST. Leave at least 1-3/4" of the end block when trimming the end, and do not cut or notch the web area of the OPEN JOIST floor truss. For the most part, framing with OPEN JOIST is no different than framing with dimension lumber. See similar questions...

No. You only need a bearing of 1-1/2" in all normal loading situations; therefore, trusses can be butted together over a 2x4 intermediate bearing wall. See similar questions...

The assembly process for OPEN JOIST floor trusses results in some unavoidable glue runs and spills. The glue can be scraped from OPEN JOIST trusses or painted over if the trusses are to be left exposed. See similar questions...

A <span> tag is another type of container tag. It is by default an inline element, which means it appears along with other content, filling each line before moving on to the next. This is how text normally appears on web pages. Note that there are rules regarding the placement of different types of elements: block level emements can not be contained by inline level elements. For example, one cannot place a div inside a span. See similar questions...

Yes you can, but keep the tubing away from the fixture and insulate the tubing in proximity of the fixture and follow manufacturers instructions. See similar questions...

A JJI-Joist is a structurally engineered timber joist, combining high-grade softwood flanges with an engineered composite panel web. For more information please see our Product Range. See similar questions...

We have three video clips of the draw span opening on this site: the east-half opening, the west-half opening and both sides of the draw span opening. See the differences from the newer west-half and the older east-half in how they open. After the project is completed, the east-half draw span mechanism will match the west-half draw span mechanism.

We design and manufacture from single pieces of kit, i.e. vibratory conveyors right through to turnkey operations. See similar questions...

Most of my systems will last 3-5 four years each depending on the client's styling and maintenance techniques. Having two systems will give you 4-8 years of hair. That's 2-3 times as long as systems of other companies. For you I would design an ultra-minimal system. They are extremely thin systems that are almost impossible to feel. Their life span is half that of my more durable systems. They will last 3-5 years for the pair of systems. See similar questions...
