STEEL CITY

Steel City is a brand historically associated with electrical enclosures, floor boxes, and related infrastructure for commercial and industrial construction. The product line available through 3G Electric focuses on nonmetallic and metallic floor box covers and carpet flanges, which are used to close and protect in-floor electrical, data, and communication connections. These covers are typically installed in raised-floor or slab-on-grade applications where access to wiring is required while maintaining a flush or semi-flush surface. The covers are manufactured from materials such as polycarbonate, plastic, and brass, and are available in rectangular and round shapes. Common dimensions include rectangular covers measuring 8 1/8 inches by 5 1/8 inches by 3/16 inch, and round covers with diameters of 6 inches or 6 3/8 inches. Rectangular brass covers measure 4 5/8 inches by 6 1/8 inches by 9/16 inch. Color options include gray, brown, black, beige, and brushed gold. These covers are designed to be compatible with corresponding Steel City floor boxes, providing a system approach to in-floor power and data distribution. The nonmetallic covers are constructed from impact-resistant polycarbonate or plastic, which offers dielectric properties and resistance to corrosion. The brass covers provide a metallic option with a brushed finish. 3G Electric supplies these Steel City floor box covers and carpet flanges as part of its broader catalog of industrial electrical equipment. The product range includes multiple SKUs covering different shapes, materials, and colors to match specific installation requirements. 3G Electric provides datasheets, specification details, and logistics support for global delivery. Technical buyers can reference part numbers such as 664-CST-SW-GRY, P 68 DRC BRN, 68R-CST-BLK, 664-CST-SW-BGE, 664-CST-SW-BLK, 664-CST-SW-BRN, and P 64 CP when specifying or procuring these components. The covers are intended for use in commercial offices, data centers, educational facilities, and other environments where underfloor wiring is present. Installation typically involves securing the cover to a compatible floor box and, in carpeted areas, using a carpet flange to transition between the floor covering and the box. The nonmetallic covers are suitable for applications where non-conductive materials are preferred, while the brass cover offers a metallic finish for architectural or durability requirements. 3G Electric maintains inventory and provides quotation support for these SKUs, enabling procurement specialists to source specific configurations without minimum order complications. The product data includes dimensions, materials, and manufacturer part numbers to facilitate cross-referencing and substitution where appropriate. For plant engineers and maintenance managers, these covers represent a replaceable component in floor box assemblies, and having access to exact-fit covers reduces downtime during repairs or renovations. The availability of multiple color and material options allows matching existing installations or specifying new ones according to project specifications. 3G Electric does not manufacture these products; it distributes them as part of its portfolio of industrial electrical components. The company serves a global customer base, shipping to various regions and providing documentation to support customs and compliance requirements. Buyers should verify compatibility with their specific floor box model and installation conditions, as cover dimensions and mounting methods can vary. Datasheets for each SKU are available upon request or through the product listing.

Guides & Resources

Frequently asked questions

Common questions about STEEL CITY from 3G Electric.

What materials are used in Steel City nonmetallic floor box covers?

Steel City nonmetallic floor box covers are made from polycarbonate or plastic. For example, the 664-CST-SW-GRY rectangular cover is polycarbonate, while the 68R-CST-BLK round cover is plastic. These materials provide impact resistance and dielectric properties. Polycarbonate covers are available in gray, beige, black, and brown. The round covers with carpet flanges are available in black or brown plastic. Material selection affects durability and appearance; polycarbonate generally offers higher impact strength than standard plastic. Verify the specific material for each SKU in the product datasheet.

What are the dimensions of Steel City rectangular floor box covers?

Steel City rectangular nonmetallic floor box covers, such as the 664-CST-SW series, measure 8 1/8 inches in length, 5 1/8 inches in width, and 3/16 inch in height. The rectangular brass cover, model P 64 CP, measures 4 5/8 inches in length, 6 1/8 inches in width, and 9/16 inch in height. These dimensions are critical for ensuring fit with the corresponding floor box and for flush mounting in the floor surface. Always confirm the cutout dimensions of the floor box before ordering.

Are Steel City floor box covers compatible with standard floor boxes?

Steel City floor box covers are designed for use with compatible Steel City floor boxes. Compatibility depends on the specific box model and cover shape. Rectangular covers typically fit rectangular boxes, while round covers fit round boxes. The carpet flange versions are intended for carpeted installations. It is recommended to cross-reference the floor box manufacturer part number with the cover part number. 3G Electric can provide datasheets to assist with verification. Do not assume interchangeability with other brands without checking dimensions and mounting hole patterns.

What is the purpose of a carpet flange on a Steel City floor box cover?

A carpet flange on a Steel City floor box cover, such as the P 68 DRC BRN or 68R-CST-BLK, provides a transition between the floor box and carpeted flooring. It allows the cover to sit flush with the carpet surface while protecting the wiring connections below. The flange typically extends beyond the box opening to cover the cut edge of the carpet. This helps prevent debris from entering the box and provides a finished appearance. Carpet flanges are used in commercial offices, hotels, and other carpeted environments where in-floor power or data access is required.

What colors are available for Steel City floor box covers?

Steel City floor box covers are available in several colors to match different floor finishes and aesthetic requirements. Nonmetallic rectangular covers come in gray, beige, black, and brown. Round nonmetallic covers with carpet flanges are available in black and brown. The brass rectangular cover has a brushed gold finish. Color selection is typically based on matching the surrounding floor or carpet. For example, brown covers may blend with dark carpet, while gray or beige may suit lighter floors. Confirm color availability for each SKU when ordering.

Can 3G Electric provide datasheets for Steel City floor box covers?

Yes, 3G Electric provides datasheets for Steel City floor box covers upon request. These datasheets include dimensions, materials, color options, and manufacturer part numbers. For example, the datasheet for 664-CST-SW-GRY would list its 8 1/8 inch by 5 1/8 inch by 3/16 inch size and polycarbonate construction. Datasheets assist engineers and procurement specialists in verifying specifications and ensuring compatibility with existing floor boxes. 3G Electric also offers logistics support for global delivery. Contact 3G Electric with the specific SKU or part number to request documentation.
