What we manufacture
Four cores. One standard of build.
Every door leaves the shop with a labeled core, a WDMA "A" grade veneer or plastic-laminate face, and the hardware machining your schedule calls for — built to ANSI/WDMA I.S.1A and AWI Section 1300.

03
Fire-rated
MC5-45, MC5-60 & MC5-90 — 45-, 60-, and 90-minute labeled assemblies in agrifiber and mineral cores, ITS-WHI listed.

Lead-lined
PC-7 — a lead-lined 7-ply particleboard core for radiation-shielded openings in imaging and dental suites.
How a Stellar door is built
A labeled stack, edge to edge.
Commercial doors are specified by their construction. Here's the section every Stellar door is built to — read from the face inward.
- AFaceWDMA "A" grade wood veneer (book & running match standard) or decorative plastic laminate.
- BHDF crossbandHigh-density crossband that stabilizes the face and resists telegraphing.
- CStilesBonded structural composite lumber stiles on each vertical edge for hardware hold and durability.
- DCoreParticleboard, SCL, agrifiber, or mineral — chosen for the use and fire rating.
- ERailsBonded top and bottom rails that close out the stiles and carry hinge and lock machining dimensions.

Common questions
Before you send the schedule
Yes. Pre-fitting, beveling, lock and hinge mortising, and other hardware preps are available. Top rail, bottom rail, stiles, and special blocking can also be specified to meet specialized hardware requirements — just send the schedule and templates.
They can. The MC5 fire-rated doors take the same WDMA "A" grade veneer faces as the PC-5 and SCL-5 standard doors, so a rated opening reads identically to the non-rated doors beside it.
Interior use only. Every door carries a full warranty for the life of the original installation; there is no exterior warranty.
Any commercially available wood veneer, WDMA "A" grade, with book & running match as standard. MDO, primed hardboard, and decorative plastic laminate faces are also available, with matching or pre-finished hardwood edges.
