Raker Beams
Heldenfels Enterprises’ precast raker beams provide the critical inclined support structure for stadium seating systems, engineered to efficiently transfer combined axial and shear loads while managing the dynamic forces generated by thousands of spectators.
These specialized structural elements feature optimized cross-sections that maximize strength-to-weight ratios, reducing demands on foundations and supporting columns while maintaining the stiffness necessary to control vibrations and deflections during events.
Our advanced manufacturing capabilities accommodate the complex geometries required for varying seating angles and architectural configurations, with integral connections that speed field assembly and ensure proper load transfer throughout the structural system. The controlled casting environment produces consistent concrete quality and precise reinforcement placement essential for public assembly structures, where safety factors and vibration criteria are paramount.
From high school stadiums to professional arenas, our raker beams deliver the structural backbone that supports tiered seating while meeting stringent building codes and providing decades of reliable performance under continuous crowd loads and environmental exposure.

Delivery & Installation
On average, prestressed concrete walls 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
Prestressed concrete wall panels excel in demanding structural applications where both load-bearing capacity and durability are critical. These versatile components serve as shear walls in multi-story buildings, retaining walls for highway projects, and perimeter walls for industrial facilities requiring blast resistance. In stadium construction, prestressed walls form vomitory passages and support massive seating loads, while in marine environments they provide corrosion-resistant barriers for port facilities and seawalls. The prestressing technology enables taller, thinner walls that maximize usable space in commercial and institutional buildings, where clear heights and open floor plans drive project value.

Frequently Asked Questions
What are typical size limitations for prestressed wall panels?
Prestressed wall panels can typically be manufactured up to 14 feet wide and 50 feet tall, though transportation and crane capacity often determine practical limits. Panel weights generally range from 10-40 tons depending on dimensions and thickness. Your precast manufacturer can optimize panel sizing to balance structural requirements with handling and shipping constraints.
How do prestressed wall panels connect to the overall structural system?
Panels connect through embedded plates, weld plates, and reinforced connections designed to transfer both gravity and lateral loads. Connection details are engineered to integrate with foundations, floor diaphragms, and roof structures while accommodating building movements and thermal expansion. Standard connection types include bolted, welded, and grouted options.
What fire ratings can prestressed concrete wall panels achieve?
Fire resistance ratings of 2-4 hours are standard for prestressed wall panels, depending on thickness and concrete cover. Most building code requirements can be met without additional fireproofing. Specific ratings depend on panel configuration, with solid panels typically providing higher ratings than insulated sandwich panels.
How are openings and attachments accommodated in prestressed panels?
Openings for doors, windows, and MEP systems are formed during casting for precise dimensions. Embedded plates and inserts for attachments are positioned during manufacturing based on project requirements. This eliminates most field cutting while providing connection points for cladding, equipment, and architectural features.
What tolerances can be expected with prestressed wall panels?
Manufacturing tolerances typically maintain dimensions within industry standards of ±1/4 to ±3/8 inch depending on panel size. Camber and deflection are calculated during design and controlled through prestressing levels. Erection tolerances follow PCI guidelines to ensure proper fit and alignment with adjacent building components.
