325S / 324S
FingerGuard™ Insulated Commercial Steel Sandwich Doors
* This model is only available in the Eastern/Central US markets at this time
Insulation is standard on the 325S standard-duty (25 gauge steel) and the 324S heavy-duty (24 gauge steel) commercial steel sandwich doors. In addition, FingerGuard™ pinch-resistant section joints promote safety and reduce risk of injury.
As with all our commercial models, traditional Hörmann quality is evident with our layered panel bonding construction process. First, hot dipped galvanizing is applied to the steel substrate, followed by a baked-on polyester base coat, then a durable baked-on polyester finish coat. This layering creates a long-lasting surface finish for maximum protection against adverse effects of the elements. This steel finish is applied on both the inside and outside door skins which are then bonded to a HCFC-free polystyrene core. The 2” thick door panel has an R-value of 8.9 for enhanced energy efficiency and sound-dampening qualities, and polystyrene insulation fills the top of the door channel for maximum insulation.
Our unique precision hinges with solid pivoting shaft minimize wear on moving parts for a long service life. All center hinges have a steel reinforcing backer plate, and along with a deep tongue and groove section profile adds to overall structural integrity. Heavy-duty between-section-seals perform as gaskets between section seams, reducing air infiltration.
Choose from four popular colors: white, brown, sandstone, or industrial grey. For ultimate customization, our Galaxy Paint System offers custom colors to match any color under the stars.

Panel Construction
The industry leader in innovative door safety, insulation, and strength

Special heavy-duty material performs as a gasket between sections to reduce air infiltration while enhancing the insulation properties.
Prevent fingers from getting caught between the door sections and reduces the risk of injuries and possible worker’s compensation claims.
Our 3-layer steel front and back construction with insulating polystyrene core increases energy savings.
Galvanized finished painted steel provides superior corrosion resistance for years of trouble-free performance.
Keeps out wind, rain, debris and other elements for added energy savings.

Section Detail
Modern Classic panels are constructed using heavy duty commercial grade extruded aluminum stiles and rails. Choose from one of our beautiful anodized or solid powder coat finishes. Obscure and tinted glass as well as solid aluminum and expanded metal panels are also available.
Hörmann Innovations
Engineering Excellence
Our unique precision hinges with solid pivoting shaft minimize wear on moving parts for a long service life.
All center hinges have a steel reinforcing backer plate for added structural integrity, and a deep tongue and groove section profile adds to the overall structural integrity and longterm performance of the door.
Safety
Our uniquely designed FingerGuard™ pinch-resistant section joints prevent fingers from getting caught between the door sections. This supports safety and reduces the risk of injuries which may result in worker’s compensation claims.

Protection from the Elements
Carefully selected commercial grade materials maximize protection from outside elements. The between section seal is constructed of a special heavy duty material that performs as a gasket between section seams to reduce air infiltration while enhancing the insulation properties of the door.

Durability
For maximum protection against the elements, a long lasting surface finish, and reduced maintenance costs, 325S and 324S door panels are constructed by first applying hot-dipped galvanizing to the steel substrate. Then, a baked-on polyester base coat and a durable baked-on polyester finish coat are added creating an exceptional product.
