Classic Car Restoration:

History

Colonnade began trading fifty years ago on the Wembley Trading Estate. The main source of business
was the chromium
plating of  bumpers for the car manufacturing industry. Gradually the market for
steel bumpers declined and new avenues had to be explored. It was during the
mid 1980's when prices
in classic cars began to increase dramatically that the market for restored cars really took off. From that
day forward we have concentrated our efforts on developing the skills and equipment required for the
restoration of metalwork to show standard.



In House polishing:        
          Polishing is an art that  isn't taught in schools or colleges. The necessary
                                            skills are invariably passed from person to person and developed over many
                                            years. All of the polishers at Colonnade were taken on as apprentices and
                                            taught in exactly the same way. It is for this reason that we can gaurantee
                                            an equal level of excellence on all orders passing through the polishing shop.



''Triple Plating''                          
You will often hear people talk about or see adverts boasting ''double'' or
                                            ''triple'' plating. This is a misleading term often used to confuse people into
                                            believing they are getting a high quality finish.
                                            Bumper bars and overiders should always be plated to surface condition four.
                                            The British Standards Institution set these standards and describe condition
                                            four as for items in ''service outdoors in exceptionally severe corrosive conditions''
                                            The only way to achive SC4 is to plate the item with pyrophosphate (heavy)
                                            copper or semi bright nickel first, and then follow up with the usual bright nickel
                                            and chrome. Extra coatings of bright nickel, or a thin coating of cyanide copper
                                            will only achieve surface condition three, which is not sufficient.
                                            Our pyrophosphate copper and semi bright nickel baths are both over six feet
                                            long, and can therefore accomodate even the largest American bumpers.



Repair Service:                            Bumper Bars: 
Bumpers are the most common items to be found in need of
                                       
            some attention. Over the years they corrode, and when involved in a collision
                                            can literally fall to pieces. With the help of the heavy copper tank, holes can be
                                            filled and dents and twists re-shaped giving an overall finish that should be
                                            superior to when they first came off the production line.
                                            Occasionally bumpers are too rotten or too badly damaged for repair. If a
                                            replacement original cannot be found, the bumper can be passed to our metal
                                            workers who are able to reproduce accurate copies.

                                            Mazac and Aluminium:   Logos and motifs were sometimes made from brass,
                                            but later models tended to be cast with zinc alloy (or ''monkey metal'' as it's
                                            sometimes known) This has a tendency to go brittle over a perion of time and
                                            breakage's frequently occur. Because re-casting is very expensive and often
                                            inaccurate it is preferable to try and rescue damaged castings. Although not an
                                            easy process, it is possible to repair and replate zinc die castings and return them
                                            to their orignal state at a fraction of the cost of re-casting.
