is metal frame doors are bettor tha wooden frame doors?
yes try going for powder coated aluminum finish for doors or windows. durable and less of taking care as for wood need to paint or polish them, metal get corroded though aluminum is expensive but worth it
Metal framed doors are probably the best for security purposes, but seem to always succumb to rust. Wood, if not properly maintained, will also deteriorate and are typically not the greatest for security. You might try taking a look at composite or PVC!
Metal framed doors are typically chose in order to comply with commercial fire codes. That is why schools and other public buildings have them. The doors are rated by the amount of time that they will hold back a fire. This allows these buildings to contain a potential fire, by compartmentalizing, similar to the function of bulkheads on a ship. For residential purposes, most people choose wood, for the beauty of the finish. Most homes don't require fire doors. except to isolate an attached garage.
metal frames come in 2 flavours - aluminium and steel. both have their advantages and drawbacks, but are better than timber doors in a number of ways. you should select a polyester powder coat finish (dual colour is now available ie 2 different colours for inside and outside) for a virtually maintainence free finish whereas timber will need regular maintainence. the lifespan of metal over timber is quite considerable, many steel windows fitted into 1930's properties are still in very good condition and have many serviceable years left in them (aluminium hasnt been around as long as steel so lifespan cannot be compared to steel). the sections used for metal are much slimmer than timber allowing more light into the property. metal is available for domestic situations and is not only used for fire rating purposes. steel is inherently stronger than aluminium and in most applications stronger than timber also, making unauthorised entry more difficult (ie cannot be drilled or cut easily). downside is cost - steel is most expensive in short term, but when lifespan and maintenance are factored in, works out cheapest (aluminium will not last as long as steel due to construction methods ie steel is welded, aluminium is screwed at joints). steel is also hot dipped galvanised prior to polyester powder coating, guaranteeing a corrosion free lifetime (1930's windows were not galvanised and are still around, so galavanised will last a lot longer). metal windows and doors can also be double glazed to comply with current building regs.
