We are not the largest manufacturer in this category. What we do differently is make it practical for small and mid-sized buyers to get hardware built the way they need it, without the volumes a large factory would demand.
Most factories in this category will not quote below several thousand units. We will. Orders from 100–200 pieces require no tooling and no mold fee.
We operate high-precision laser marking equipment in-house. Your logo goes onto the product itself — not a sticker — and it does not add weeks to your lead time. Even at small quantities, you can sell under your own brand.
We are equipped with high-precision laser machines and offer small-batch customization services, perfectly suited for the personalized needs of retail customers.For small orders of 100–200 pieces, no molding is required and there is no high MOQ.We can quickly complete laser branding, enabling customers to build their own brand even with limited order quantities.
Manufacturing Capability
Our Guangdong facility combines CNC machining with in-house laser marking, allowing us to run small batches without the tooling costs that normally make short runs uneconomical.
What this means for you:
- No mold fee on orders from 100 pieces
- Laser branding completed in-house, not outsourced
- Colour box packaging available for retail-ready shipments
- Physical samples before you commit to production

Our Promise: German Standards, Global Trust, Zero Compromise
Our panic exit devices are manufactured in accordance with EN 1125 specifications. Full technical specifications — material, backset, door thickness range, fire rating, handing — are published on every product page so you can verify compatibility before you contact us.
Our Unique Certifications Tell Our Story
• DIN 18251: German Engineering DNA
• EN 12209: European Safety Framework
• ISO 26262: Automotive-Grade Security (industry first)
• Werner Protocol: 0.1mm Touch Standard (handcraft heritage)
Unlike others who test to pass, we test to surpass. Our Guangdong facility's 0.003% defect rate beats German averages by 60%. Why? Because when you combine German systematic with Chinese patience, you don't get compromise—you get evolution.
Trust Werner's great-grandson when he says: "We're not the oldest lock company, but we're the only one where 1920 craftsmanship meets 2024 possibility, creating locks that remember their makers while protecting your future."
