ACO KlassikDrain Type 436Q Slotted Galvanized Steel Grate - 0.5 Meter

Product Details: ACO KlassikDrain Type 436Q Slotted Galvanized Steel Grate - 0.5 Meter

Galvanized steel grates are the general-purpose grate family for the ACO KlassikDrain K100 and KS100 4" trench drain systems, engineered to capture and convey stormwater across commercial and industrial applications. Grates in the 100 series are shared across both edge-rail materials, so a single part number fits galvanized-rail K100 channels and stainless-rail KS100 channels alike. The galvanized family spans perforated, slotted, longitudinal, and mesh patterns in 1 meter and 0.5 meter lengths, with EN 1433 load ratings that run from Class A pedestrian duty up to Class E heavy industrial duty, and several patterns carry ADA-compliant, heel-resistant ratings. Every grate secures to the channel with ACO's boltless DrainLok or QuickLok locking, and because the grate fitted determines the realized load class of the installed system, grate selection is the key specification decision for any K100/KS100 run.

The Type 436Q (ACO part number 31551) is the 0.5 meter Class E slotted grate of the family — the half-length companion to the 1 meter Type 435Q, sized to cover 19.69" (500 mm) half-meter channel sections and to finish out runs where a full-length grate will not fit. Formed from 16 gauge galvanized steel, it is rated to EN 1433 Load Class E at 134,885 lbs (1,856-2,785 PSI) for heavy industrial duty on K100, KS100, and H100K-8 runs. Its dual slot pattern — 1.75" x 0.38" and 1.17" x 0.38" openings — delivers 17.6 square inches (113.5 sq cm) of intake area across the half-meter grate, and the grate carries Bicycle Safe, Anti-Slip, and LEED credentials. The "Q" stands for ACO's patented QuickLok boltless locking system: the grate stud push-fits into the stainless steel spring clip of a QuickLok locking bar, sold separately (channel locking bar part 02899, Series 900 catch basin bar part 98717). At 6.8 lbs, the grate unlocks and lifts out easily whenever the trench needs to be inspected or cleaned.
