What MI Products does

MI Products is a privately held UK specialist manufacturer of door and window threshold systems, architectural ironmongery, and locking mechanisms, founded in 1997 and headquartered at Middlemarch Business Park, Coventry. The company designs and produces a focused portfolio of low-threshold products (FX15, LTH1, LTH 2015, Patio LTH) and the patent-pending Secure4Life patio door locking and threshold system, alongside ancillaries (weather seals, shootbolt strikers, brush piles, patio stops, retaining brackets) and patio door hardware (handles, tandem-roller wheels). Products are constructed from aluminium and PVCu combinations with internal thermal breaks and integrated drainage manifolds, engineered to satisfy UK Building Regulations (Part M, Document Q), security standards (PAS 24, Secured by Design), and weather performance (BS6375), validated through independent testing at pressures up to 250 Pa and 50,000+ operational cycles.

The company operates a horizontal B2B sales model, selling directly to Profile System Companies, Hardware Distributors, and Window & Door Fabricators throughout the UK, with documented integration approvals from VEKA, Eurocell, Selecta, and KOMM profile systems. Revenue is generated primarily through hardware product sales, supplemented by a bespoke product design and development service offered free of charge, with manufacturing supplied for exclusive customer designs. Pricing is quote-based with no publicly disclosed list prices, and customer engagement is conducted via direct outreach, phone, and website inquiries rather than digital self-serve channels. The business is led by Director Ian Searle and operates with 11–50 employees, with no external investors, parent company, or funding rounds disclosed in the available source material.
