Digital maturity, built with no e-commerce past.

Weinmann Aach is a German steel and metals distributor with a reputation for efficiency — and, when it set out to modernise, no meaningful e-commerce experience to build on.

Where they started

The company wanted to advance its digital capabilities, but it knew software alone wouldn't get it there — moving a complex steel business online demanded strategic advice, not just a storefront. After seeing Slize running in a peer's warehouse, inspired by the Damstahl shop and its proven results, Weinmann Aach concluded that Slize was the only platform that could genuinely handle its requirements.

We didn't just need a webshop. We needed a partner who understood our products, our certificates and our pricing — and could help us build the digital foundation to grow on.

The solution

Slize is purpose-built for the complexity of B2B commerce: a composable, modular and scalable platform designed for industries with intricate products and processes. For Weinmann Aach, that meant handling kilograms, metres and bundles alongside value-added services such as cutting, galvanizing, sandblasting and stamping — all within a single order flow.

Material certificates, carrying the chemical and mechanical properties that steel, medical and chemical customers depend on, became available to download on demand. Pricing could be fixed or dynamic, chosen per product line across billions of possible combinations. And the platform integrated cleanly with ERP and PIM in real time — keeping continuity even while the company runs multiple ERPs through a transition.

Beyond the technology, Slize acted as a digital consulting partner, helping Weinmann Aach build the right foundation for long-term growth — the part a standard webshop can never offer.

The results

Weinmann Aach implemented a platform tailored to its industry’s complexity, simplified the handling of certificates, multi-unit products and pricing, and gained the in-house expertise to keep building. Most importantly, it is now prepared to scale — and to weather future ERP transitions without disruption.
