英语翻译我们工厂选择的都是最好的材料,是经过全球多家客户验证过的.并且上次返工的时候,最终客户的工程师已经看到我们做的实

回复邮件晚了,应该先道歉,所以把“另外,周三下午和周四,我在外地出差,没有及时回复您的邮件,不好意思.”放在邮件开始比较好,比较有诚意.
Please excuse my late reply to your mail. I was on a business trip on Wednesday and through Thursday.
To answer your question, our plant selects the best-quality material which has been verified by our global accounts. During the last on-site visit, the engineer of our end-user already saw the finished product with his own eyes, and he accepted the material we used. So the material will not be an issue of concern. Please rest assured.
Kind regards,
