Lush Heat Treatment

What Lush Heat Treatment does

Lush Heat Treatment is a UK-based metallurgical services company headquartered in Hatfield that provides vacuum and air heat treatment for precision-engineered components used in commercial and military aerospace, defense systems, and space programs. Its process capabilities span solution treatment, annealing, normalizing, hardening and tempering, vacuum aging, precipitation hardening, argon and nitrogen quenching, air processing, degreasing, and hardness testing, delivered through vacuum furnaces that include one of the largest working zones available in the market. The company is differentiated by Nadcap Gold Merit status, ISO 9001:2015 certification, and explicit customer approvals for data card signoff from Rolls-Royce (Civil & Defence Aerospace), BAE Systems (including Regional Aircraft), Marshall Aerospace, and Meggitt.

In 2026, Lush Heat Treatment was acquired by Global Precision and repositioned as the Thermal Treatment Division within a vertically integrated precision manufacturing platform that includes four other divisions — Engineered Products, Precision Gears, Advanced Coatings, and Tubing Technologies — and operates from eleven centers of excellence across four countries. The integration is intended to keep heat treatment inside the parent company's production chain, reducing handoffs for customers running critical programs with tight lead times. The division operates as a B2B specialty industrial services provider, monetizing thermal treatment capacity enterprise-by-enterprise through direct engagement with major aerospace and defense primes, with no publicly disclosed pricing.

The division's go-to-market is enterprise field sales driven, targeting prime contractors whose program needs cannot tolerate furnace turnaround delays. Its market position is anchored on the regulatory and customer approvals portfolio it has accumulated over decades, including a reported nearly century of metallurgical experience inside the team. As part of Global Precision's five-division platform, the Thermal Treatment Division serves as a critical in-house step that supports mission-critical applications where supply chain failure is not an option.
