The Pre-Shipment Inspection (PSI) is one of many types of quality control inspections conducted by Gladman Iron Doors. This inspection is done according to standard QC Test, or based upon customer requirements. Samples are selected and inspected for defects at random, according to these standards and procedures. For us, Pre-Shipment Inspection is an important step in the quality control process and is the method for checking the quality of aluminium french doors before they are shipped.

Through the years, Gladman has been a qualified manufacturer and supplier of french doors with full glasses. We are engaged in product design and production. Gladman's iron door frame series contains multiple sub-products. The amount of light being reflected from its surface is always sufficient. Its surface is generally coated with barium sulfate or titanium dioxide accompanied by magnesium carbonate. Every department of Gladman has its clear responsibilities to work out best aluminum windows together.

We stick to the policy of "surviving by the quality and seeking vitality by innovation". We will make every effort to produce quality products and offer considerate service to the customers and society.
