HOLLAENDER

Hollaender Manufacturing Company is a US-based producer of structural pipe fittings and handrail systems, with a history dating back to the early 20th century. The brand is known for its line of aluminum and steel components that assemble without welding, using set screws to create rigid tubular structures. The product range includes elbows, tees, crosses, flanges, and other fittings in multiple pipe sizes, as well as pre-assembled handrail sections. These components are used to build guardrails, safety barriers, racks, and frames in industrial, commercial, and institutional settings. Hollaender fittings are typically made from aluminum or steel, with mill or black finishes, and are designed to accommodate standard pipe outer diameters. The handrail sections are floor-mounted, round, and available in two-rail configurations, with or without toe boards. 3G Electric supplies Hollaender products globally, offering 84 SKUs that cover common pipe sizes and configurations. The catalog includes aluminum elbows for 1 in and 1 1/2 in pipe sizes, with actual outer diameters of 1 3/8 in and 1 7/8 in respectively, as well as steel and aluminum handrail sections measuring 5 in x 5 in. These items are stocked for quick fulfillment and are supported by 3G Electric's technical team, who can assist with component selection and system integration. The fittings are suitable for applications requiring corrosion resistance, such as chemical plants, food processing facilities, and outdoor walkways. The handrail sections provide fall protection along platforms, stairs, and mezzanines. 3G Electric maintains inventory of Hollaender parts and can ship to project sites worldwide, with documentation available for specification and procurement. For engineers and maintenance managers, the modular nature of Hollaender systems allows for on-site modifications and repairs without specialized welding equipment. The set-screw design enables rapid assembly and disassembly, which is beneficial for temporary structures or areas requiring frequent access. The aluminum components offer a balance of strength and weight, while steel options provide higher load capacity. 3G Electric's online catalog provides detailed specifications, including material, finish, and pipe size compatibility, to facilitate accurate ordering. The company also offers quote requests and technical support to ensure correct part selection. With a focus on industrial safety and structural integrity, Hollaender products are a practical choice for handrail and guardrail systems. 3G Electric's global distribution network ensures that these components are accessible to projects regardless of location, with efficient logistics and customer service.

Frequently asked questions

Common questions about HOLLAENDER from 3G Electric.

What pipe sizes are available for Hollaender aluminum elbows?

Hollaender aluminum elbows are available for multiple nominal pipe sizes. In 3G Electric's catalog, common options include elbows for 1 in pipe (1 3/8 in actual outer diameter) and 1 1/2 in pipe (1 7/8 in actual outer diameter). These elbows create 90-degree turns in tubular structures and are used in handrail, rack, and frame assemblies. The fittings are made from aluminum with a mill finish and are designed to work with standard pipe. For other sizes, consult the full Hollaender range or contact 3G Electric for availability.

Are Hollaender handrail sections available in both steel and aluminum?

Yes, Hollaender handrail sections are offered in both steel and aluminum. The steel versions typically have a black finish, while aluminum sections come in a silver finish. Both are floor-mounted, round, and feature two rail levels. They measure 5 in x 5 in and are supplied without toe boards unless specified. These sections are used to construct safety barriers and guardrails along walkways, platforms, and stairs. Material selection depends on factors such as required strength, corrosion resistance, and weight considerations.

What is the finish on Hollaender structural pipe fittings?

Hollaender structural pipe fittings are commonly supplied with a mill finish, which is a standard untreated surface for aluminum and steel. This finish is suitable for indoor applications or where additional coating is applied after installation. Some fittings may also be available in other finishes; however, the standard catalog items from 3G Electric are mill finish. For specific finish requirements, verify with 3G Electric's technical team to ensure compatibility with the intended environment.

Can Hollaender handrail sections be used for fall protection?

Hollaender handrail sections are designed for use in safety barriers and guardrails, which can contribute to fall protection systems when installed according to applicable codes and standards. The sections are floor-mounted and feature two rail levels, providing a structural framework for guardrails. However, fall protection requirements vary by jurisdiction and application. It is the responsibility of the specifying engineer to ensure that the complete system, including components and installation, meets relevant safety regulations. 3G Electric supplies the components but does not provide engineering certification.

How does the set-screw design of Hollaender fittings benefit installation?

Hollaender fittings use set screws to secure pipe connections, eliminating the need for welding or threading. This allows for rapid assembly and disassembly using basic hand tools. The design is advantageous for on-site modifications, temporary structures, or maintenance activities where access is limited. It also reduces the need for hot work permits and specialized labor. The resulting joints are rigid and can be adjusted if needed. This modular approach is common in industrial environments where flexibility and speed of installation are important.
