with galvanised steel or other metals without concern for galvanic corrosion.

Hollaender has introduced two new Speed-Rail fittings designed specifically for installation of solar racking systems in areas that experience extreme wind. The fittings include a tee and elbow for use with 2" IPS pipe. The ability to withstand uplift caused by wind loads is critical in solar pipe racks. While most regions of the USA must design for 90mph winds, certain coastal areas such as South Florida and the Gulf Coast must design for 135mph and higher wind speeds. On a Speed-Rail fitting, the component that produces pipe holding power is a single integrated proprietary internal/external reverse-knurl cup-point set screw that securely attaches the fittings to the pipe, and provides tremendous resistance to loosening and pullout. The new fittings are designed with two set screws, producing a substantial increase in pullout resistance. Testing on the 2" IPS fitting shows the addition of the second set screw increases pullout capacity from 3,900 pounds to 8,200 pounds on galvanised pipe – an increase of 110 per cent. Speed- Rail slip-on pipe fittings are used with

A Speed-Rail fitting and pipe solar rack system installs quickly and securely, especially when compared to welded and other more complex systems. The only tools required for assembly are a saw, hex key and tape measure. Hollaender is a manufacturer and marketer of aluminium structural pipe fittings, aluminium pipe, and infill panels, as well as final assemblies that use these components. Its products are used in the design and build of handrail, guardrail and safety rail systems, as well as a wide variety of modular pipe and fitting based structures for commercial, residential, public works, industrial applications, retail store fixtures and other structural applications. The components and systems are marketed under the trademarked brands Speed-Rail ® and Interna-Rail ® . Hollaender also offers consultation, design and project management services.

aluminium, galvanised steel, stainless steel or black iron pipe to easily build solar panel racking systems. They are strong and lightweight, and are available in a wide variety of fixed and adjustable configurations, including the tees and flanges most commonly used in solar panel installations. The versatility of the fittings allows dependable support structures to be constructed virtually anywhere a solar panel needs to be installed. The same versatility also allows the systems to be easily uninstalled and moved, if necessary. All fittings are made of 535.0 aluminium-magnesium. They are backed by a ten-year warranty against corrosion, will not rust, and can be used
