G&O Springs

What G&O Springs does

G&O Springs Ltd is a UK-based precision spring manufacturer established in 1973 in Redditch, specialising in safety-critical spring components for aerospace, defence, subsea/oil-and-gas, and nuclear applications. The company offers eight spring material families (Titanium, Stainless Steel, Nimonic, Inconel, Hastelloy, Elgiloy, MP35N, Carbon Steel) produced through three manufacturing routes (CNC Autocoiling, Flowline, and Mandrel Coiling) and complemented by NADCAP-accredited in-house special processes including heat treatment (AMS2750), non-destructive testing (ASTM E1417 / MIL-STD-1907 Grade A), passivation (ASTM A380 / AMS2700 Method 1 Types 7 and 8), and mechanical testing (ASTM E8 / A370). The business operates under an AS9100:D / ISO 9001:2015 quality system with AS9100 Design accreditation and runs an APQP/PFMEA framework aligned to AS9145/AS13004.

Commercially, G&O operates a custom quote-based B2B model with multi-year programme contracts, selling directly to international aerospace primes and tier-1 integrators such as Rolls-Royce, Safran (Messier Bugatti Dowty), Meggitt (three divisions), Sikorsky, Moog, Ultra Electronics, Fokker, UTAS, and distributor Incora under VMI arrangements. The go-to-market is enterprise field sales complemented by a multilingual springs.aero website (10 languages) and direct technical/quote/quality email channels; no resellers, distributors, or e-commerce channels are used. The family-owned firm employs 11–50 staff at its single Redditch site, with no external institutional investment disclosed.

Revenue is generated through project-based contract manufacturing orders with custom specifications per customer, augmented by free design reviews and collaborative engineering support using Institute of Spring Technology software as customer acquisition and retention tools. Sales motion is anchored in long qualification cycles (customer-specific approvals such as SABRe 3, SCREQ-001-PRIDE, EDQP6, QAM 101, PUR-SOP-003, QM002, QAP 7-4-01, and SQA-001) and operational integration via Vendor Managed Inventory with key accounts.

Core offering

G&O Springs manufactures precision springs for aerospace, defence, and safety-critical applications. The company produces springs in eight material families (Titanium, Stainless Steel, Nimonic, Inconel, Hastelloy, Elgiloy, MP35N, Carbon Steel) using CNC autocoiling, flowline, and mandrel coiling methods, complemented by in-house NADCAP-accredited special processes including heat treatment, NDT, and passivation. It also provides collaborative spring design engineering using Institute of Spring Technology software.

Product overview

G&O Springs is a precision spring manufacturer serving aerospace, defence, and safety critical applications. The company operates a unified manufacturing and engineering platform offering eight distinct spring material types (Titanium, Stainless Steel, Nimonic, Inconel, Hastelloy, Elgiloy, MP35N, and Carbon Steel) across three manufacturing methods (CNC Autocoiling, Flowline, and Mandrel Coiling). The portfolio includes three specialized processes (NDT, Passivation, Heat Treatment) and a web-based Squareness Calculator tool. All products and services are unified under AS9100:D quality certification with NADCAP accreditations for aerospace-grade precision manufacturing.
