The success of TG GRISET’s production of copper and copper alloys are also due to its engineering services that orchestrate the construction, master the assembly of and organise the successful launch of multiple laminating equipment (rolling mills, cleaning lines, annealing lines…) around the world.

264 years of innovation enrich your and our present.

GRISET is one of the oldest family owned businesses in the world today (over 260 years and spanning 8 generations). Antoine Griset started the first precious metals foundry workshop in the “Marais” district of Paris in 1760. By the end of the 18th Century, his son Antoine Alexandre put in place the first rolling mills, which were powered either by man or horse.

- In the beginning of the 19th century, GRISET rolled the platinum bar which was used for the production of the "Standard Meter".

- In the middle of the 19th century, GRISET had at its disposal the 17 rollers powered by a 40 HPA steam engine.

- GRISET received the gold medal at the Universal Show (World Fair) in 1878.

- At the end of the 19th century, GRISET became the first to roll aluminium.

- At the start of the 20th century, GRISET began to diversify by making metal rivets.

- By the mid 1900’s, GRISET created GRISET Engineering, a unit that develops, builds, installs and commissions rollers, cutters, furnaces, … on a world wide basis.

In 1985, GRISET developed a new method of producing a double gauge sheet through plated stamped/rolling, for the electronic market.

In 1997, the German group DIEHL acquired GRISET.

In 2012, BAVARIA Industriekapital AG became the sole shareholder and partner of GRISET.

In 2014, To strengthen its strategic position, GRISET SAS created with TNMG, first China’s producer of copper, a joint venture, TGTEM, for the production of double-gauge strips for the Chinese market of power transistors.

Located in TONGLING (Province of ANHUI, west of Shanghai), TGTEM (TONGLING GRISET TONGGUAN ELECTRONIC MATERIALS Co. LTD) intends to develop a close collaborative partnership with Asian customers by offering this electronic market, experience, flexibility, quality and competitiveness.

In 2016, GRISET is taken over by the Chinese group TNMG (TONGLING NONFERROUS METAL GROUP) and becomes TG GRISET. With more than 1 million tons of copper, this mining group producer and transformer of copper is a major global actor.
