Structural steel, fine-grain structural steel to S1100, Hardox 400/500 and stainless steel 1.4301/1.4571.
Contract manufacturing, no minimum order
Single parts, assemblies, prototypes and small series are all manufactured alike.
EXC3 & ISO 9001
Certified execution of load-bearing steel components with internal quality assurance and NDT on request.
Structural Steel Fitting in Contract Manufacturing
Structural steel fitting forms the craft foundation for the production of mechanical assemblies and steel structures. At Bock Maschinenbau this covers cutting, drilling, thread tapping, deburring and the precise fitting of steel parts to drawing.
Our construction mechanics and fitters work directly with machining, welding and steel fabrication – all trades under one roof. This allows short routes and efficient contract manufacturing even for small quantities and single parts from batch size 1.
Materials: structural steel S235 to S355, fine-grain structural steel, Hardox, stainless steel 1.4301/1.4571 and special alloys. Components from a few kilograms up to 50 tonnes are safely handled and positioned with the 2×25 t overhead travelling crane.
Jig Building for Special Purpose Machinery and Steel Fabrication
Jig building covers the design and manufacture of clamping, welding and assembly aids for dimensionally accurate work. Welding jigs ensure the reproducibility of component positions and reduce reject rates in series production.
Bock manufactures welding jigs, assembly gauges, grippers and special fixtures to customer specification. Re-clamping fixtures for the handling of heavy steel parts as well as inspection gauges for quality assurance are also part of the contract manufacturing scope.
Structural steel fitting and jig building at Bock are integrated directly into the manufacturing chain: cutting, flame cutting, welding, blasting and painting from a single source. On-time delivery – single parts and small series to customer requirements.
Materials for Steel Fitting
Steel fitting and assembly at Bock cover all common structural and special steels:
- Structural steel S235, S355 – Standard structural steel
- Fine-grained structural steel up to S1100 – high-strength, weldable
- Hardox 400 / 500 – wear-resistant steel for high-stress components
- Stainless steel 1.4301, 1.4571 – corrosion-resistant
- Special steels to drawing and customer specification
Material certificates and full material traceability are provided on request or in line with project requirements.
Typical Applications
Steel fitting and jig building at Bock are used for:
- Assembly of crane jibs, frames and load-bearing steel structures
- Tacking and welding jigs for long girders and profiles
- Assembly of pipe systems and structural connections
- Precise joining and positioning of heavy assemblies prior to final welding
Joined components pass directly into welding within the same facility — MAG and submerged-arc certified, TIG by qualified welders.
Impressions from steel fitting and jig building
Views: hand-finishing inside a rolled XXL shell course on the welding turning rolls – and the same component twice, the drum shell before assembly with its turned outer surface, drilled hole pattern and flange bolt circle, and after assembly and painting, completed with ring gear, bearing pedestal and base plate. Plus a welded pipe bend assembly with a flange ring, built from rolled segments.

Frequently asked questions about steel fitting and jig building
Which work steps does steel fitting in contract manufacturing cover?
Steel fitting at Bock Maschinenbau covers cutting, drilling, tapping, deburring and the precise fitting of steel parts to drawing. This includes the precise joining and positioning of heavy assemblies before final welding, as well as tacking and welding jigs for long girders and profiles. Single parts, assemblies, prototypes and small series are manufactured from batch size 1.
Which fixtures are built in contract jig building?
Bock designs and manufactures clamping, welding and assembly aids to customer specification: welding jigs, assembly gauges, grippers and special fixtures, re-clamping fixtures for handling heavy steel parts, and inspection gauges for quality assurance.
Are the joined parts welded in the same company after the steel fitting work?
Yes. Joined components pass directly into welding in the same company; cutting, oxy-fuel cutting, welding, blasting and painting are integrated with the steel fitting work into one production chain.
For which catchment area are steel fitting and jig building undertaken?
Bock undertakes steel fitting, jig building and assembly work at the Lorch plant for companies from the Ostalbkreis, the Stuttgart area and the DACH region. Delivery is ex works Lorch or carriage paid.
