HOLLAENDER

HOLLAENDER is a manufacturer of aluminum and steel structural pipe fittings, handrail systems, and framing components, with a product line centered on slip-on fittings for mechanical tubing and schedule pipe. The brand is known for its Speed-Rail, Nu-Rail, and Rackmaster product families, which are used to build handrails, guardrails, shelving, and industrial structures without welding or threading. HOLLAENDER fittings are cast from aluminum alloy (typically A356 or 6061-T6 equivalents) and are available in mill finish or anodized gray; steel components are fabricated from carbon steel with a black or yellow powder-coat finish. The product range includes crosses, tees, side outlet tees, adjustable cross tees, external couplings, corner connectors, and handrail sections, covering pipe sizes from 1 1/2 in to 2 in nominal (with actual outer diameters up to 2 3/8 in). Fittings are designed for use with Schedule 40 or 80 pipe and meet ASTM B26 or ASTM A53 material standards where applicable. HOLLAENDER handrail sections are offered in round profiles, floor-mounted or wall-mounted configurations, and include options without toe boards. The brand’s structural pipe fittings are rated for indoor and outdoor applications, with corrosion resistance inherent in aluminum components. 3G Electric stocks 67 SKUs of HOLLAENDER products, including crosses, tees, couplings, handrail sections, corner kits, and aluminum framing pipe. Inventory covers mill-finished aluminum fittings, anodized aluminum pipe bundles, and painted steel handrail components. 3G Electric provides logistics support for global shipment, enabling procurement teams to source HOLLAENDER fittings for railing systems, pipe structures, and modular framing projects without minimum-order constraints typical of direct manufacturer supply. The catalog includes adjustable cross tees for variable-angle connections, side outlet tees for branch runs, and external couplings for straight pipe extensions. Handrail sections are available in 5 in x 5 in profiles with floor-mounted rail mounting, and corner kits provide pre-assembled 90-degree turn solutions. All HOLLAENDER products supplied by 3G Electric are new, factory-original components, with manufacturer part numbers cross-referenced for specification verification.

Frequently asked questions

Common questions about HOLLAENDER from 3G Electric.

What pipe sizes do HOLLAENDER structural pipe fittings accommodate?

HOLLAENDER fittings in the 3G Electric catalog are designed for nominal pipe sizes of 1 1/2 in and 2 in. For 2 in fittings, the actual outer diameter accommodated is 2 3/8 in, which corresponds to Schedule 40 steel pipe or aluminum pipe with matching OD. The 1 1/2 in fittings accept pipe with a 1.9 in actual OD. Always verify the actual outer diameter of your pipe against the fitting specification before ordering.

Are HOLLAENDER aluminum fittings corrosion-resistant for outdoor use?

Yes, HOLLAENDER aluminum fittings are inherently corrosion-resistant due to the aluminum alloy composition. The mill finish provides a natural oxide layer that protects against atmospheric corrosion. Anodized gray finishes offer additional surface hardness and UV resistance. However, in marine or highly corrosive environments, galvanic corrosion may occur if fittings contact dissimilar metals without isolation. For such applications, use dielectric barriers or select stainless steel alternatives.

Can HOLLAENDER handrail sections be used without toe boards?

Yes, the HOLLAENDER handrail sections stocked by 3G Electric (SKUs 39K850 and 39K860) are specified as 'Toe Board Not Included.' These sections are designed for applications where toe boards are not required by local codes or where separate toe board systems are installed. The handrail sections are 5 in x 5 in in profile, floor-mounted, and available in steel (black) or aluminum (silver). Always consult your local building code for toe board requirements.

What is the difference between a HOLLAENDER adjustable cross tee and a standard cross tee?

A standard HOLLAENDER cross tee (e.g., model 11E-8) provides fixed 90-degree branch connections. An adjustable cross tee (e.g., models 19-9 and 19-6) allows the branch arm to rotate and lock at various angles, typically from 0 to 90 degrees, enabling non-perpendicular pipe runs. Adjustable cross tees are used for sloped handrails, angled shelving, or custom structural frames. Both types are available in aluminum with mill finish for 2 in pipe.

Does HOLLAENDER offer aluminum framing pipe compatible with their fittings?

Yes, 3G Electric supplies HOLLAENDER aluminum framing pipe (SKU 54XN48) in 1 1/2 in nominal size with a 1 7/8 in actual outer diameter and 96 in overall length. This pipe is anodized gray for corrosion resistance and is designed to work with HOLLAENDER slip-on fittings of the same nominal size. The pipe is sold in bundles of five 8-ft lengths. Always confirm that the pipe OD matches the fitting's intended pipe size before assembly.

What mounting styles are available for HOLLAENDER handrail sections?

The HOLLAENDER handrail sections in the 3G Electric catalog are floor-mounted. The rail mounting style is specified as 'Floor Mounted' for both steel and aluminum variants. These sections are designed to be anchored to concrete or structural floors using base flanges or post brackets (sold separately). For wall-mounted or ceiling-mounted applications, additional HOLLAENDER brackets or adapters may be required, which are not included in the standard handrail section SKUs.
