巴西采购需求：人体工学椅、电脑桌、办公设备、集装箱办公室、游戏椅、会议桌

I am looking for a durable steel storage solution for archiving files and documents. The shelf should be weather-resistant and designed to securely store items in a safe and organized manner. It would be great if it comes with locking mechanisms to ensure confidentiality and protection. Additionally, I would like to know more about the various sizes and configurations available. Please provide information on materials, design features, and any customization options. A prompt response would be appreciated as I am keen to finalize my procurement soon. Thank you!
