- All glasses shall be inspected as following steps:

 Scratches or faults which can be easily seen

 Chips or other faults

 Assure that all angles are well covered ( vacuum glass)

 Signal to differentiate glass catergories

 Glass thickness

 Glass size and area

 Distortion of surface due to processing

 The position for marking should be bottom corner to read easily

 Glass egde

8.2 Aluminium

Aluminium materials such as horizontal, vertical frame, other sections when transported to site, they shall be separated with a piece of wood to prevent from being scratches, damages, also cover by plastic to protect during transportation

The aluminium surface shall be painted with electrostatic layer PVDF technique or Powder coasting All those aluminium bars shall be inspected as:

 Straight

 Chip

 Surface scratches

 All surfaces are painted

 Faults on surfaces can be seen and not accepted

 Horizontal and vertical bars or scractches

 Inspect the thickness of paint

8.3 Sticking Glue

There are 3 types of glue shall be used: DOW CORNING 791 Silicone Weatherproofing, DOW CORNING 795 Structural Silicone Buiding và DOW CORNING 983 Structural Silicone Buiding Those shall be inspected specification, stored in cold room with temperature under 25oC The using date shall be shown on package, sent glue shall be in usable time limitation at least 4months since expire date

All Silicone shall be checked and recorded as following steps:

 Besides storing all glue into cool room, they shall be store according to manufacturers

 Determination of completing QC daily and other documents as proofs

8.4 Mattress and block of mattress

Those shall be inspected as the following steps:

 Kind of required mental and materials

 Ex-work certificate

8.5 Complex steel

Complex steel shall be inspected as the following steps:

 Complete, paint or zinc steep as requireemnt

 Processing

 Ex- work certificate and necessary transportation

8.6 Embed

This shall be inspected as the following steps:

 Processing

 Completed painting (or steep into hot zinc)

 Ex- work certificate and necessary transportation

 Detail inspectation
