Pemko 228D 36 – Frequently Asked Questions

1) Will the Pemko 228 floor plate work as an ADA-compliant transition between two different floor heights?
That is what the 228 is for. It is a floor plate 8 inches wide and 1/4 inch high, laid over the joint between two flooring levels so foot traffic and wheels cross without a lip to catch. Pemko states it meets ADA requirements and the ANSI/BHMA A117.1 accessibility standard. The 1/4 inch height matters here: at that height the plate itself does not create a new obstacle, and the 8 inch width gives the ramp run to feather the transition.
2) What lengths does the Pemko 228 threshold come in, and can I get one for a wider opening?
Stocked lengths are 36, 48, and 72 inches, in either mill finish aluminum or dark bronze anodized aluminum. Beyond that, the 228 is fabricated to order anywhere from 24 inches minimum to 185 inches maximum, so a single piece can run a wide storefront or a corridor opening. Custom drilling can be specified with the cut length, and pieces can be welded into an assembly for openings that turn a corner or exceed a single run.
3) How do I fasten a Pemko 228 floor plate down, and are screws included?
Pemko calls for support every 4 inches on center and at every welded seam, using SMS #10 x 1 inch fasteners. That spacing is close for a reason: an 8 inch wide plate at only 1/4 inch thick will flex and drum underfoot if it is anchored at the ends only. Order the #10 x 1 inch sheet metal screws and the appropriate anchors for your substrate separately, and plan the hole layout before the plate is set, or have the drilling done as part of the custom fabrication.
4) Can a Pemko 228 be used at a fire-rated door opening?
Yes. The 228 Series is UL 10C certified, which is the positive pressure fire test for door assemblies, so it can go under a rated opening. It is also BHMA certified. For an institutional or healthcare inspection, that UL 10C listing is the line item the AHJ looks for on threshold and floor plate hardware.
5) Is the Pemko 228 a saddle threshold that seals a door, or something different?
Different part. The 228 is a flat floor plate, 1/4 inch high across an 8 inch width, meant to cover and smooth a floor transition. It has no raised saddle profile, no bumper, and no groove for a door sweep or weatherstrip. If you need to seal an exterior door against water and air, you want a saddle or bumper threshold with a stop and a seal, not this. If you need to cover a slab joint, a flooring height change, or an old threshold cutout inside the building, the 228 is the right shape.
6) Does the Pemko 228 come with non-slip tread, or is that an option I have to specify?
The anti-slip surface is PemKote, and it is an option rather than standard, so it has to be called out on the order. On a lobby entry, a wet-traffic corridor, or a kitchen doorway, specify it. On a dry interior transition it is not needed and the plain aluminum surface is fine.
7) Which Pemko 228 finish should I order to match existing door hardware, mill or dark bronze?
Two finishes are offered: mill finish aluminum, which is the plain silver-grey mill surface, and dark bronze anodized aluminum. Mill matches aluminum storefront and clear-anodized frames. Dark bronze matches bronze-anodized storefront systems and dark frames, and the anodizing gives a harder, more colorfast surface for a floor plate that gets walked on daily. Both finishes are offered in all three stock lengths of 36, 48, and 72 inches.
8) Will an aluminum floor plate hold up to cart traffic and floor scrubbers in a commercial building?
The 228 is aluminum alloy, which handles corrosion, wet mopping, and scrubber use without rusting, and Pemko specifies it for office, retail, healthcare, education, industrial, and multi-tenant residential work. The thing that decides durability is the fastening, not the metal: at 1/4 inch thick, support every 4 inches on center is what keeps a cart wheel from working the plate loose. Anchor it to that spacing and it stays flat.
9) I need to cover a floor joint longer than 185 inches. Can I run two Pemko 228 plates together?
Yes. The 228 is made to be welded into custom assemblies, so runs longer than the 185 inch single-piece maximum are handled by joining pieces. Pemko requires support at every welded seam in addition to the 4 inch on center spacing, so the joint gets its own fasteners rather than spanning free. Give the fabricator the total run and any turns and the pieces come cut to suit.
10) I am replacing a worn threshold in an apartment doorway. Will the Pemko 228 cover the old fastener holes?
Usually, yes. At 8 inches wide the 228 is wider than most saddle thresholds it would replace, so it laps over the old anchor holes and the wear pattern rather than sitting inside it. Two cautions. It is a flat plate, not a saddle, so it will not seal an exterior unit door against weather. And it stands 1/4 inch proud of the floor, so check that the door bottom or sweep still clears before you set it.
11) Can Pemko 228 floor plates be ordered pre-drilled for a specific hole pattern?
Yes. The 228 is fabricated to specific size and drilling requirements, so the hole layout can be set at the factory instead of on site. Give the cut length and the hole positions, keeping fasteners no more than 4 inches apart on center and adding one at each welded seam. On a large job this is worth doing, since drilling an 8 inch plate to a consistent pattern in the field across dozens of openings is where installs slow down.
