The 152 x 89 UB16 universal beam is a structural steel section manufactured from S355J0 structural steel and supplied with a red oxide primer finish. It is commonly used for lighter horizontal load-bearing steelwork, building openings, secondary beam supports, mezzanine structures, structural frames and other construction projects where this specific UB section has been specified by a qualified structural engineer.

The 152 x 89 dimensions are nominal section sizes used to identify this universal beam profile within UK steel schedules. With an approximate weight of 16kg per metre, this section is typically selected where a lighter horizontal structural steel beam is required within an engineered design.

152 x 89 UB16 Universal Beam Overview

This UB16 universal beam is designed for structural use when specified correctly as part of an engineered design. Universal beams are most commonly used as horizontal members to support loads across openings, spans and structural frames.

The final beam size, length, bearing details, connection design, support conditions and installation method must always be confirmed by a qualified structural engineer before ordering.

Steel Grade and Section Size

This universal beam is supplied in S355J0 structural steel. S355J0 is a commonly used structural steel grade with a minimum yield strength of 355 MPa, making it suitable for a wide range of structural steelwork applications when correctly specified.

The section is identified as 152 x 89 UB16, meaning it has a nominal depth of 152mm, a nominal width of 89mm and an approximate weight of 16kg per metre.

For exact flange thickness, web thickness, root radius, dimensions, masses, tolerances and section properties, refer to BS EN 10365:2017, published steel section tables or the applicable mill certificate where available.

Red Oxide Primer Finish

This universal beam is supplied with a red oxide primer coating. Red oxide is commonly used as a shop primer or temporary protective coating during handling, storage and installation.

Red oxide should not be treated as a permanent anti-corrosion system. If the steel will be exposed to moisture, external conditions or a corrosive environment, a suitable final paint or coating system should be applied.

Storage and Handling

Red oxide primer provides temporary surface protection only. Steel sections should still be stored in a dry, ventilated area before installation and should not be left exposed to wet or corrosive conditions for long periods.

If the section will be visible, exposed or used outdoors, it should be prepared and protected with a suitable final coating system before installation or final use.

Approximate Weight

This section weighs approximately 16kg per metre. As a guide, a 6m length weighs approximately 96kg before allowing for any packaging or handling variation.

Steel sections are heavy items and customers must arrange suitable labour or lifting equipment for safe offloading.

Common Uses

The 152 x 89 UB16 universal beam is commonly specified for domestic and light commercial steelwork, building openings, secondary beam supports, mezzanine structures, fabricated steel frames and horizontal load paths within engineered steel systems.

Actual suitability depends on the span, load, bearing length, connection design, support conditions, installation method and overall structural design.

Cut Lengths and Returns

This universal beam can usually be cut, drilled, welded and fabricated using suitable equipment and correct preparation. If you require a specific cut length, please leave a note at checkout or contact us before ordering to confirm availability.

Cut-to-length steel is made to order and non-returnable unless faulty. Please verify all dimensions, lengths and specifications with your engineer before ordering.

Structural Steel Notice

This product must be specified by a qualified structural engineer and used in accordance with approved drawings, building control requirements and applicable UK standards, including BS EN 1993-1-1 where relevant.

Rackerman does not provide structural design advice and cannot confirm whether this section is suitable for your opening, span, load or installation. The customer is responsible for ensuring the correct steel section has been specified before ordering.

Delivery Information

Lead times are currently 5–10 working days. Orders are scheduled for delivery as early as availability allows. Universal beams and structural steel sections are heavy items, so suitable delivery access is required. Offloading assistance is required on site.

Deliveries are kerbside only. Our lorries do not have HIABs or lifting equipment, so the steel must be safely handballed or offloaded by the customer upon arrival.
