Flex or deflection in glass units is to be expected, and even instances of 30mm – 50mm of deflection is deemed safe and normal for some larger glass units.

They need to be frequently cleaned with the panel surface receiving warm soapy water (washing up liquid is suitable) and wipe dry softly with a soft cloth.

This will be limited to Fensa qualifying installs only.

When replacing glass units under guarantee we will do so on a like for like basis. If an exact replacement is no longer available, we will supply the nearest equivalent available. Due to the natural coatings changing from time to time there may be shade or colour variations in replacement units.) Our guarantee does not cover the cost of specialist handling or lifting equipment needed to replace products under guarantee in cases where the need arises because access to the site has become more difficult since installation, or if specialist handling or lifting equipment was used during the original installation.

Powder Coating – Our powder coated products (excluding pressings & trims), are guaranteed for a period of 10 years period for paintwork, against fading or corrosion for marine environments. We follow the guidelines set out by Qualicoat (15th edition) for the quality of our powder coating.

Bedford Bi Folds ltd use RAL ‘Classic range’ codes to identify colours used in paint. RAL codes can be the same across different manufactures and there may be shade or colour variations. We can provide samples of our RAL colours, however these may also have subtle variations from the actual final product and are indicative only. When trying to match up to other products supplied by third parties, Bedford Bi folds Ltd cannot accept liability if the RAL code is of a different shade.

Bedford Bi Folds Ltd do not cover paint quality on the internal section of the profile which cannot be seen when the product is in a closed position.

We guarantee powder coated products for 5 years against fading and or corrosion when products are installed between 500m and 5.6km from high tide saltwater environments, providing a marine grade finish has been specified. This does not cover pressings or trims.

When we are installing powder coated products within 500 meters of the high tide saltwater line, we cannot guarantee the powder coated material because the salt air is more corrosive. It will be the client’s responsibility to inform Bedford Bi folds Ltd of the site’s specific location at point of enquiry, Bedford Bi Folds Ltd can then let the client know of any such terms applied to the guarantees.

We cannot guarantee the colour or paintwork quality of the thermal break (plastic polyamide between aluminium sections), which can be susceptible to colour change, paint flaking over time or lack of powder coating during the paint finish. The colour or paintwork on the thermal break cannot be altered post powder coating. It is your obligation to regularly maintain and clean the stainless-steel elements of products supplied to you, to maintain their appearance. A lightweight cloth or nylon brush should be used. At no time should any scouring brush or abrasive be used on any product as this may damage or scratch the stainless steel.

Where stainless steel is sited near to the sea or in an area where there is heavy atmospheric dirt and or traffic film should receive more regular cleaning, otherwise brown staining may appear on the stainless steel.

If regular cleaning is not carried out, our quality guarantee will be void. Dependent on the product, it is possible that the discoloured stainless- steel item cannot be replaced, and the complete product would need to be replaced to restore the original appearance. In these circumstances we will only be able to replace the product on payment of the prevailing market price.
