Are you sure about this? See how wrong a man can be.

Yeah I know about copper and other row materials but they only begin to fall now. I also have Sweden’s largest steel manufacturer in the neighbouring town SSAB and they almost selling their entire production to China and the plant run for full gas. Not like the photographic businesses.

A very close friend of mine has a big iron work and he told me that prices run high because of China as I recall he said that steel suppliers don’t even have fixed price lists any longer as the price changing day by day so they went over to the call in and check basis.
Well I’m not into this that much but I know for sure that platinum not getting cheaper so as gold which I use to tone.
We are getting off-topic, but...
Here's a relatively recent (and short) article concerning China's steel exports for October and the year of 2006 through that time:

This is not contrary to your observation about the Sweedish steel plant. China does not produce "specialty steels" in large amounts - they still rely on companies in the EU, Japan, and USA for these materials. If this facility produces such steel, then it is likely to be running at very high capacity.
As for commodity prices, they are listed in USD - which has been steadily losing value. As a result, the prices have increased considerably in the past 5 years. This affects China, as well as the USA, since their currency is closely coupled to the USD.
Both gold and silver are used as hedges against drops in currency. If uncertainty over the purchasing power of currencies increases - they will appreciate in value. Today, for example, when the US FOMC indicated they were somewhat less concerned about inflation, the dollar fell. And silver and gold all increased in value.
China's stock market fell 5% today, by the way, over concerns about inflation and the country's need to tighten up monetary policy to prevent banks from making too many bad loans. The dollar fell, and silver, gold, and platinum all increased in price. If the dollar drops substantially (always possible) then commodity prices could still increase even if demand for them slows (let's say China really clamps down on their banking system).
So, whether China slows or not, I don't expect your gold and platinum will stop getting more expensive regardless of what steel, copper, or anything else does. That goes double for silver.
There are a lot of people out there in the world worried about the US dollar and other currencies...
