A view of a roof using common purlin framing.

The purlins are marked in red.

This view is from the inside of the building, below the roof.

The rafters are the beams of wood angled upward from the ground.

They meet at the top of the gable at a ridge beam, which has extra bracing to attach it to the rafters.

The purlins are the large beams perpendicular to the rafters; from this shot, it appears that there are three purlins on either side of the roof.

The sheathing boards are sometimes called the roof deck and are painted white.

Aluminium composite material panel structure.

A sandwich panel is any structure made of three layers: a low-density core (PIR, mineral wool, XPS), and a thin skin-layer bonded to each side.

Sandwich panels are used in applications where a combination of high structural rigidity and low weight is required.

Bending along rolls.

Roll forming, also spelled roll-forming or rollforming, is a type of rolling involving the continuous bending of a long strip of sheet metal (typically coiled steel) into a desired cross-section.

The strip passes through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired cross-section (profile) is obtained.

Roll forming is ideal for producing constant-profile parts with long lengths and in large quantities.

Hangzhou (or; Standard Mandarin pronunciation), also romanized as Hangchow, is the capital and most populous city of Zhejiang, People's Republic of China.

It is located in the northwestern part of the province, sitting at the head of Hangzhou Bay, which separates Shanghai and Ningbo.

Hangzhou grew to prominence as the southern terminus of the Grand Canal and has been one of China's most renowned and prosperous cities for much of the last millennium.

Its West Lake, a UNESCO World Heritage Site west of the city, is among its best-known attractions.

A study conducted by PwC and China Development Research Foundation ranked Hangzhou first among "Chinese Cities of Opportunity".

According to the Globalization and World Cities Research Network (GaWC), the city is classified as Beta (global second-tier) city, together with Chongqing, Nanjing and Tianjin in China.

Hangzhou is also one of the world's top 100 financial centers, according to the Global Financial Centres Index.

Overhead stick welding.

Welding is a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion.

Welding is distinct from lower temperature techniques such as brazing and soldering, which do not melt the base metal (parent metal).
