Architectural Details


1-3/4″ thick doors are readily available in standard 3×7′ or 4×8′ sizes, and as single or double doors. Custom sizes (smaller or larger) are available – consult with Weiland.


Premium 25-mil gelcoat is molded into our fiberglass doors, chemically bonding with the underlying fiberglass resins. This exterior protects against corrosion, and provides a highly-cleanable surface. Most customers opt for UV resistant white doors, however gray or custom gel coat colors are available. Consult with Weiland for advice.

Seamless Fiberglass

Most door companies construct doors using fiberglass “plates” or “skins” that are laminated to a stile and rail. Weiland stands apart from all other doors on the market, by being the only door molded all at once. The front, back, and sides are formed at once through an advanced close-molded process (Light RTM), meaning that the door is a solid structure of fiberglass. Measuring .1875 inch thick on the face and nearly .375″ thick on the edges, Weiland’s fiberglass exterior is the thickest of any door in the industry.


Weiland offers multiple 16-ga stainless steel frame styles, and high quality molded fiberglass frames (not to be confused with pultruded fiberglass which is not acceptable). Stainless frames are available in 304 or 316 alloys, as mill finished (2B) or brushed (#4). Multiple frame styles exist such as solid/welded frames for concrete walls (typically 5-3/4” deep), narrow depth welded frames to slip into a capped-off IMP openings, or our popular two-part / split frame to sandwich over a varying thickness of IMP walls or combo wall. Molded fiberglass frames are available as well if extra thermal considerations are required. Please consult with Weiland on requirements and recommendations.


Weiland doors are built for food and dairy processing. That means every door is built to the following standards: void free, plastic lumber styles, rails and hardware backing, polyurethane foam core (2 lb closed cell foam). Any other option would be less-than-acceptable for our customers.

Stainless Steel Vision Panels

We stock 20×32″, 12×18″, 5×20″, and 10×10″ frames, and can special order any custom size. We provide scratch resistant polycarbonate glazing in most applications (which is much more durable and chemical resistant than standard Lexan), and can also provide insulated, tempered, heated and safety coated glass, depending on the environment.

Pre-Mounted Hardware

Weiland stocks a sizable inventory of commercial grade 1 door hardware. Weiland’s preferred hardware supplier is Dorma, however, every brand and model is available to our customers. We can recommend hardware that offers both quality and value. 95% of our doors are shipped pre-hung in the frame with the hardware pre-mounted, and ready for a quick installation. This eliminates last minute surprises on the job site, missing hardware, wrong preps, etc., and ensures a quality product and positive door experience.
