02 / 07 Service

Metal processing

Precision in steel, stainless steel, and aluminum. Our machinery covers the entire range: sawing, bending, rolling, and welding. From a simple bent part to a complex assembly, we manufacture your components dimensionally accurate to drawing — flexibly as a single piece or in a series.

03 / 07 Industrial installation in production hall

Industrial installation

We get it in place. Our experienced fitters take care of the professional assembly of steel constructions, platforms, and systems directly on your site. We seamlessly integrate new components into your existing infrastructure — safely, cleanly, and without disrupting operations.

04 / 07 Service

Inspection per BGV D6, D8, BGR500

Operational safety with proof. As qualified persons, we carry out the legally required UVV inspections on your cranes, winches, and load-bearing equipment. We inspect with legal certainty according to the current DGUV regulations, document defects, and ensure liability-safe operation of your lifting equipment.

05 / 07 Service

Blasting

The perfect bonding base. Through professional blasting, we remove scale, rust, and old coatings from workpieces down to the pores. This optimal surface preparation is crucial for the durability and quality of all subsequent painting or finishing processes.

Repair service

Quick help in case of downtime. When something gets stuck, we are there. Our flexible service repairs defective metal components, impact damage on railings, or wear parts on systems. We repair professionally instead of just replacing — saving costs and minimizing downtime.

WHY FRANZ KLOTZ GMBH

What makes our work so special

01 / 03 Advantage

Custom work instead of standard

In industrial metalwork, no off-the-shelf solution fits. Whether complex platforms, stair towers, or safety installations: we plan and manufacture exactly according to your structural conditions and requirements. Where others stop, our custom designs only begin.

02 / 03 Advantage

Official seal of approval for your safety

When it comes to load-bearing structures and safety-relevant components, we make no compromises. As a certified welding specialist company under DIN EN 1090-2 and a specialist company under AwSV, we guarantee you legally compliant quality and tested safety for your infrastructure.

03 / 03 Advantage

From planning to installation

Save yourself the coordination of various trades. We offer you the full service: from structural planning and design, through manufacturing, to professional installation on-site. One contact person, one project, one clean execution.

PROCESS & WORKFLOW

How a project unfolds

01 / 06

Request

Send us your inquiry — whether a finished specification, building plan, or a simple hand sketch. We review your documents without obligation and check initial technical feasibility and capacities.

02 / 06

Consultation

We leave nothing to chance. Our experts clarify technical details, advise you on material choice (e.g. corrosion protection class), and, if needed, take measurements directly on-site. This way we guarantee everything fits later.

03 / 06

Quotation

Transparency instead of hidden costs. You receive a detailed fixed-price quotation with a clearly defined scope of services. For complex steel structures, we already include the structural pre-dimensioning and the schedule for your planning security.

04 / 06

Production

Precision "Made in Germany". After your approval, we create the construction plans and manufacture your components in our halls. Sawing, drilling, and welding (certified per DIN EN 1090) take place under strict quality control.

05 / 06

Installation

On time and safe. Our qualified installation team delivers the components and takes care of the professional assembly. We integrate steel constructions, platforms, or systems precisely into your existing infrastructure — without unnecessarily disrupting your operations.

06 / 06

Acceptance

Safety with official seal of approval. After completion of the installation, the joint acceptance takes place. You receive complete documentation, all material certificates, and — where necessary — proof of UVV inspection for legally secure operation of your system.

INDUSTRIES & APPLICATIONS

Where our designs make the difference

Metalwork for industry means more than just welding. It's about structural engineering, durability, and legal compliance.

We understand the requirements of large industrial facilities — from chemical resistance in process industry to structural load capacity in heavy machinery construction. Our solutions integrate seamlessly into your production.

01 / 04 Industry

Industrial construction and infrastructure

Hall construction, platforms, and access

So your employees can safely reach every corner of the facility. We manufacture and install steel platforms, stair towers, walkways, and railings per DIN EN 1090. Individually fitted to your hall layout, to optimize routing and eliminate accident hazards.

02 / 04 Industry

Environmental and air technology

Extraction technology and pipework

Clean air for large halls. We design heavy-duty filter housings, cyclones, and complex pipework systems for industrial extraction systems. Our sheet metal processing guarantees tight weld seams and precisely fitting transitions for efficient airflow.

03 / 04 Industry

Chemicals and process industry

Tank construction and AwSV solutions

Safety when handling water-hazardous substances. As a specialist company under AwSV, we manufacture certified containment pans, stainless steel tanks, and pipework. Resistant to acids, alkalis, and aggressive media — for environmentally compliant production.

04 / 04 Industry

Automotive and logistics

Operational equipment and impact protection

Robustness for tough material flow. We build what standard catalogs don't offer: heavy-duty racks, solid impact protection for forklift traffic, and individual transport racks. Additionally, we ensure legal certainty in operations through UVV inspections on cranes.

PROCESS ADVANTAGES

Certified safety

Quality is no coincidence — it's a standard. As a certified specialist company, we guarantee you legal certainty and verified weld seam quality.

METALWORK FAQ

The most frequent questions about metalwork

Is Franz Klotz certified for load-bearing steel structures?

Yes. We are a certified welding specialist company per DIN EN 1090-2 (EXC2). This means we are authorized to manufacture and install load-bearing structures such as platforms, stairs, or hall roofs. You receive from us the legally required CE marking and declaration of performance for your construction file.

Do you also handle on-site installation?

Of course. We don't just deliver "to the curb". Our own installation team professionally assembles the constructions (railings, racks, enclosures) on your premises and integrates them into your existing facility. We bring the necessary lifting equipment and tools.

Do you carry out UVV inspections?

Yes. We inspect your cranes, winches, gates, and load-bearing equipment according to the current DGUV regulations (formerly BGV). You receive a legally secure inspection protocol and the inspection sticker. We can often remedy defects directly afterwards — saving you a second appointment.

What materials do you process?

We process structural steel (S235/S355), stainless steel (V2A/V4A), and aluminum. Depending on the application, we offer suitable corrosion protection: from priming and high-quality industrial painting through to hot-dip galvanizing or powder coating for outdoor use.

Do you repair impact damage?

Yes, our repair service is often faster than a new build. If a forklift has damaged a railing or supports, we check the structural integrity, straighten or replace the damaged segment, and quickly restore safety.

Are you authorized to perform work in WHG areas?

Yes, we are a certified specialist company under AwSV (Ordinance on Installations for Handling Water-Hazardous Substances). We manufacture and refurbish approved containment pans, pipework, and sealing surfaces in the chemical and process industry.
