NosparoPREFER Quality and Safety: excellence that protects every environment
For over eighty years, PREFER has been synonymous with reliability, innovation and Made in Italy quality. Founded in 1941, the company is now a benchmark in the design and manufacture of locks, cylinders and security systems for a wide range of sectors: residential, industrial, commercial and public. At the heart of PREFER’s philosophy are two fundamental values: product quality and people’s safety. Every component combines technical expertise, precision craftsmanship and attention to the highest international regulatory standards.
An ISO 9001:2015-certified quality management system
For PREFER, quality is more than a promise: it is a certified commitment. The company complies with the ISO 9001:2015 standard, confirming that it has a quality management system designed to ensure controlled, traceable and continuously improved manufacturing processes. This international certification demonstrates that every PREFER lock and locking system follows specific design, manufacturing, testing and distribution criteria, ensuring reliable, long-lasting performance. Through rigorous checks at every stage, from raw material selection to the finished product, PREFER ensures superior quality standards, recognised and valued both in Italy and in international markets.
Tested, certified and guaranteed security
Security is at the very heart of PREFER’s identity. Every product is designed to withstand forced entry, impact and wear over time, using the latest technologies and exceptionally high-quality materials. PREFER locks and cylinders undergo mechanical and functional testing in accordance with European EN standards and the relevant security industry standards. Every item is individually tested to ensure correct operation, maximum resistance and long-term reliability.
These tests include:
- Mechanical strength and cycle endurance testing;
- Component tolerance and precision checks;
- Corrosion and weather resistance testing;
- Simulated forced-entry attempts to ensure maximum protection in real-world conditions.
High-quality materials and sustainable processes
PREFER’s commitment to quality also extends to material selection and manufacturing processes. We use carefully selected metals, high-performance alloys and components with a low environmental impact, sourced through traceable and monitored supply chains. Every manufacturing stage is designed to reduce waste, optimise energy consumption and minimise environmental impact, in line with our vision of industrial sustainability. This attention to raw materials not only improves the quality of the finished product but also helps maintain long-term reliability, even under intensive use or in demanding environments.
Complete control over production: 100% Made in Italy
All PREFER products are designed and manufactured in Italy, at facilities equipped with advanced technologies and staffed by highly qualified personnel. This complete control over the production cycle enables us to maintain high standards of quality and security, ensuring full consistency between design, development and the finished product. Every detail, from engineering design to machining, reflects decades of experience, expertise and passion for precision engineering. The PREFER brand is therefore synonymous with authenticity, reliability and 100% Italian quality.
Technological innovation for tomorrow’s security
Research and innovation underpin PREFER’s company philosophy. We continually invest in new technologies, materials and manufacturing processes to develop increasingly intelligent, robust and sustainable locks and security systems. With a qualified technical team and collaborations with research organisations and institutes, PREFER can anticipate market needs and offer solutions that combine mechanical security and ease of use. The goal is simple yet ambitious: to protect people and premises with innovative, reliable and certified products, designed to last and adapt to the challenges of the future.
Protecting people, premises and valuables
For PREFER, security is more than a technical requirement: it is a human value. Every lock, cylinder and component is designed to protect what truly matters — people, families, businesses, possessions and everyday peace of mind. We design systems that combine maximum resistance, ease of use and compliance with international regulations, providing comprehensive protection tailored to different applications. From locks for reinforced security doors to cylinders for complex locking systems, every PREFER product is developed with the aim of making spaces safer, more efficient and built to last.
Continuous improvement and customer focus
PREFER’s quality and security are built on one essential principle: listening to and meeting customer needs. Every piece of feedback becomes an opportunity for improvement, and every project a chance to innovate. Through an extensive distribution network and specialist technical support, PREFER provides ongoing assistance to customers in Italy and abroad, ensuring tailored solutions and compliance with each country’s regulatory standards.
