Tacke + Lindemann

What Tacke + Lindemann does

Tacke + Lindemann GmbH is a 125-year-old, family-owned German metal supplier and full-service component specialist for industrial construction, headquartered in Dortmund. The company serves customers across 35 countries with a portfolio that combines in-house manufactured metal profiles — trapezoidal and corrugated sheets in aluminum, steel, and stainless steel — and a distributed range of door, gate, door-closing, door-automation, and escape-route technologies sourced from partner manufacturers including Assa Abloy, dormakaba, GEZE, and Hekatron. The product set is organized under proprietary sub-brands such as TA-Aluform®, TA-Protect®, TA-Alutherm®, TA-Lumin, TA-Liquid, TA-Falz, TA-Steelcolor, TA-Platal, TA-Inox, and TA-Perfo, and is certified to CE, GSB Premium, Qualicoat Class 3, AAMA 2605, and ISO 12944 C5-VH classifications. The firm maintains 3,000 tonnes of metal and 5,000 door-technology articles in inventory to support rapid delivery.

The company's technology base consists of three in-house roll-forming production lines in Dortmund producing 12 profile variants (nine trapezoidal and three corrugated) and an in-house Metal Service Center with two uncoiling lines and one cross-cutting line capable of processing coils between 60 kg and 5 tonnes, with film, craft paper, or polysurlyn applied to one or both sides. This allows flexible, project-specific customization for industrial insulation, roofing, and facade applications. Object consulting (Objektberatung) wraps the products with VOB-compliant project planning, on-site technical clarification, and optional maintenance contracts, while certified first-time and refresher training programs — delivered in cooperation with supplier partners at the Dortmund site — extend the company's role into customer capability building.

Commercially, Tacke + Lindemann generates revenue through one-time sales of metal profiles and door/gate systems, metal processing services (slitting, cutting, coating), project-based object consulting for doors, gates, and locking systems, and certified training programs. The go-to-market is primarily a sales-led enterprise field-sales motion executed by specialized object consultants who accompany customers through every project phase, supplemented by an e-commerce webshop for insulation accessories and an international distribution network reaching 35 countries. The company executes more than 100 construction projects annually across hospitals, logistics centers, shopping centers, and office buildings, and is represented by Dipl.-Kfm. Daniel Tacke as authorized representative (HRB 33148, Dortmund).
