How do I buy or sell?
Use published materials and buy requests to find a starting point. Sign in to submit a listing or requirement and send proposals. Follow Buyer Connection or Seller Connection.
Why is my submission not public immediately?
Administrators review listings, buy requests and company submissions before publication. Submission is not approval or verification.
Who can read a quotation?
Proposals and deal-room messages are available to the participants and authorized administrators. Avoid putting confidential information in public listing or request descriptions.
What does acceptance mean?
It records agreement in principle. The parties arrange the final contract, inspection, payment and delivery directly. MetalSite does not hold funds or provide escrow.
Are old sellers and product adverts current?
No. The original records remain in the migration archive. Historical suppliers and demo product ads are not activated as current inventory or verified businesses.
Where are the old courses and calculators?
The University learning path replaces old class instructions. The current calculator and units guide replace obsolete Toolbox links.
Does the old auction help apply?
The current site uses listings, buy requests and private proposals. Old bidding, promotion-pack and auction-email instructions describe earlier systems or the WordPress development theme.
