FAQ
What types of locks are compatible with these Plastic & Steel door frames?+
These frames are designed to accommodate a wide range of traditional mortise locks, as well as some modern cylindrical locks. Ensure the lock you choose is appropriate for your security requirements and that the frame’s bore size matches the lock cylinder diameter.
How durable are the plastic components?+
The plastics used are engineered to be impact-resistant and weather-proof, designed to withstand typical environmental conditions. However, extreme forces or prolonged exposure to direct sunlight could potentially cause degradation over time – regular inspections are recommended.
Do I need any special tools for installation?+
Basic hand tools such as a screwdriver, hammer, and measuring tape will generally suffice. For more complex installations involving hinges or locking mechanisms, you may benefit from having access to power tools.
Can these frames be painted?+
Yes, the plastic components can be easily painted with most standard exterior paints. However, we recommend using a primer specifically designed for plastics to ensure optimal adhesion and longevity of the paint finish.
What security standards do these products meet?+
While specific certifications may vary depending on the exact product model, many are tested to BS EN 1629-3 for resistance against forced entry. Always check the manufacturer’s specifications for detailed testing information.
Are there different sizes available?+
We offer a range of sizes to suit various door and window dimensions. Please carefully measure your openings before ordering to ensure you select the correct size frame for your needs.
How do I maintain these Plastic & Steel frames?+
Regular cleaning with mild soap and water is recommended to remove dirt and grime. Avoid using abrasive cleaners or solvents that could damage the plastic surface. Periodic lubrication of hinges can also prolong their lifespan.
Are these frames suitable for external use only?+
These frames are designed for both internal and external use, provided they are properly sealed and protected from prolonged exposure to harsh weather conditions. Consider using sealant around the edges to prevent water ingress.
What is the typical lifespan of a Plastic & Steel door frame?+
With proper installation and maintenance, these frames can typically last 10-20 years, depending on environmental factors and usage. Regular inspections for signs of damage or wear will help ensure their continued effectiveness.
Can I replace individual components if they are damaged?+
Yes, many of the individual components – such as hinges and locking mechanisms – are readily available separately. This allows you to replace only the damaged part rather than the entire frame, potentially saving on costs.
