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

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...

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). See similar questions...

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...

Standard Portfolio Analysis of Risk (SPAN) is a worldwide acknowledged risk management system developed by Chicago Mercantile Exchange (CME). It is a portfolio-based margin calculating system adopted by all major Derivatives Exchanges. Objective of SPAN: SPAN identifies overall risk in a complete portfolio of futures and options at the same time recognizing the unique exposures associated with both inter-month and inter-commodity risk relationships.

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. See similar questions...

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

If a patient with cystinuria is able to prevent stones, or at least produce and pass stones without resulting in blockage of the urinary tract, there should be no cause for reduced life span. Many patients never develop renal insufficiency (poorly functioning kidneys), particularly if they are compliant with their fluid regimen. If kidney damage does not occur, and in the absence of other complicating medical problems, then life expectancy is the same as in someone without cystinuria. See similar questions...

The life expectancy of a well used Maherajah Longboard Racing Ski (and similar skis from other manufacturers) is about 5 years. Nicks and scratches in the outer layers of the ski will allow the absorbtion of water, which can make the ski heavier over time. This additional weight affects the ski's performance. Older skis aquire more flex which will cause porpoising and increased drag. See similar questions...

If you want to clear your surface to a uniform, opaque color then it is quite straightforward: /* Set surface to opaque color (r, g, b) */ cairo_set_source_rgb (cr, r, g, b); cairo_paint (cr); However, what if you want to clear the surface to something other than an opaque color.
