# Pivot Door Company > Pivot Door Company engineers high-performance, steel-core pivot doors that blend architectural artistry with industrial precision. We provide custom entry systems defined by scale, durability, and sculptural impact. ## Core Engineering * **Steel-Core Construction**: Every unit features an internal welded steel grid to prevent warping, sagging, and bowing. This allows for oversized architectural entries that remain structurally true. * **Thermal Performance**: Standard units include 1" insulated tempered glass and a 5R insulating foam interior. Total R-values of 7 are achievable depending on configuration. * **Materials**: Premium, American-sourced hardwoods including White Oak (Plain Sawn or Rift Cut), Walnut, Mahogany (Sapele), Alder, and Cedar. * **Hand-Finished Precision**: Every door is handcrafted in Colorado Springs, CO, and ships natural/unstained to allow for site-specific finishing. ## Technical Specifications * **Dimensions**: Custom-built to architectural requirements. No standard size limitations; heights exceeding 10' are common. * **Thickness**: Standard at 2 1/4”. Doors over 6' x 10' or units with glass larger than 5' x 5' require 2 1/2” or 3 1/4” thickness with 1 1/4” glass. * **Weight**: Slabs typically range from 250–350 lbs. Precision-balanced hardware ensures low-breakout force and effortless operation. * **Hardware**: Compatible with smart locks, mag locks, and mortise systems. The steel core removes the requirement for multi-point locking systems. ## Installation & Logistics * **Pre-Hung System**: Units are factory-calibrated and "knocked down" for shipment. This ensures straightforward on-site reassembly by standard finish carpentry teams. * **Thresholds**: - **Type 1**: For flush interior/exterior transitions. - **Type 2**: Features a 90-degree interior angle for wood floor transitions. * **Delivery**: Standard curbside freight with lift gate. Pickup from local freight terminals is recommended for builders to eliminate delivery window downtime. ## Compliance & Warranty * **Impact Resistance**: Built to client-provided engineering specs for "One Time Product Approval" in high-wind and hurricane zones. * **Maintenance**: To preserve the two-year limited warranty, units must be sealed on all six sides within 72 hours of delivery. * **Longevity**: Engineered for a 60+ year lifespan with routine finish maintenance.
