Frequently Asked Questions: Correx Signs London
Answers to common technical queries regarding fluted polypropylene boards, fixing, and delivery:
What is Correx and why is it used for outdoor signs?
Correx is the brand name for extruded twin-wall fluted polypropylene plastic sheeting. It has a hollow corrugated structure similar to cardboard, but is made of 100% waterproof plastic. It is exceptionally lightweight, inexpensive, weather-resistant, and tough, making it the leading choice for estate agent boards, temporary outdoor event signs, and construction site notices.
Should I choose 4mm or 6mm Correx for my application?
Choose 4mm Correx for standard estate agent boards (610x813mm), event directional signage, lamp post placards, and short-term promotions where boards are cable-tied to flat surfaces or railings. Choose 6mm Correx for larger panels exceeding 1.2 metres, high-wind construction site hoardings, or freestanding scaffolding signs where maximum columnar rigidity is required.
Why does flute direction matter when ordering Correx signs?
Correx flutes provide structural stiffness along their length. For signs mounted vertically on single posts or lampposts with cable ties, the flutes must run vertically to prevent the board from bending or creasing across the post in strong London winds. When ordering from LightPrint, our prepress team aligns flutes vertically by default unless specified otherwise.
Is Correx 100% waterproof and recyclable in the UK?
Yes. Correx is made from pure polypropylene (PP), which does not absorb water, swell, or rot in the rain. Furthermore, it is 100% recyclable under UK Resin Identification Code 5 (PP). Unlike PVC banners or vinyl-coated boards, unlaminated Correx boards can be placed directly into commercial polypropylene recycling streams after your event.
Should I order my boards with eyelets or pre-drilled holes?
Choose 11mm brass eyelets if you plan to install the signs using cable ties, rope, or bungees on wire fencing, crowd barriers, or lampposts (the nickel-plated ring prevents the plastic from tearing under wind load). Choose pre-drilled holes if you plan to screw or nail the signs directly onto wooden hoardings, timber stakes, or drywall.
How quickly can I collect printed Correx signs in London?
Because we operate industrial swissQprint flatbeds directly at our plant at 140 Mile End Road (London E1 4LJ), we offer emergency rush collection within 2 to 4 hours of artwork sign-off. We also provide same-day dedicated London courier delivery across all central and greater London postcodes.
How should I prepare my artwork for Correx printing?
Supply high-resolution vector PDF files set to 100% actual dimensions with CMYK color mode and 3mm bleed on all outer edges. Photographic elements should be 150 to 300 DPI. Keep important text and logos at least 15mm away from the board edge to avoid interfering with eyelet placement or pre-drilled holes.
How does Correx compare to Foamex and Dibond?
Correx is the lightest and most cost-effective option, ideal for temporary outdoor displays lasting up to 18 months. Foamex (solid PVC foam) is smooth, dense, and rigid, ideal for high-end indoor retail displays and exhibition shell schemes. Dibond (aluminium composite) is virtually indestructible and engineered for permanent 10-year shop fascias and architectural cladding.
