Slab Beams
Heldenfels’ Enterprises precast slab beams combine the efficiency of beam-and-slab construction with the quality advantages of offsite manufacturing, providing contractors with a rapid floor and roof system solution for commercial and industrial projects.
The precision-cast bearing surfaces and connection details ensure quick field assembly with minimal grouting and adjustment, reducing erection time by up to 50% compared to traditional cast-in-place methods. Our slab beams excel in applications requiring open floor plans and heavy load capacities—from industrial facilities and commercial buildings to institutional structures where speed of construction and quality control are paramount.
Manufactured with embedded plates for MEP attachments and designed to integrate seamlessly with mechanical systems, these components arrive ready to install, eliminating weather-dependent field operations while delivering the structural performance and long-term durability essential for modern construction.
Product Information
Technical Specs
| Standard Sizes: TXDOT Sizes 4SB12, 5SB12, 4SB15, 5SB15 | Installation: Crane ready with lifting hardware |
Delivery & Installation
On average, slab beams take about 6-8 weeks before they are ready to leave our facility. Our delivery network makes shipping fast and easy! Each project is different and your timeline will be discussed when the order is placed.
Applications & Use Cases
Slab beams are primarily used in bridge construction to support precast deck panels and distribute loads efficiently across spans. They are ideal for highway overpasses, ramps, and short- to medium-span bridges where speed of construction and durability are critical. Their prestressed design ensures high structural performance and long service life, while their compatibility with other precast elements allows for rapid installation and reduced on-site labor.

Frequently Asked Questions
What exactly is a slab-beam or precast beam supporting slab systems?
A slab-beam system combines a beam and slab: a precast beam (such as T-beam, double-tee, or rib beam) supports a slab (precast or cast-in-place) and transfers loads to columns or walls, integrating floor and bending structural functions.
What are the benefits of using precast slab-beam systems compared to fully cast-in-place systems?
They offer quality control, speed, reduced onsite labor, fewer formwork needs, and better surface finishes by leveraging factory production under controlled conditions. Also, schedule risk is lower.
Can utilities, ducts, or openings be accommodated in slab-beam elements?
Yes. Voids, conduits, sleeves, or openings can be cast into the precast beams or slabs to allow routing of HVAC, plumbing, or electrical systems.
What are the transportation, handling, and erection constraints?
Because slab-beam units can be large and heavy, transport route restrictions, crane capacity, and staging area are critical. Units are typically lifted by embedded hardware and must be designed for handling stresses during lifting.
