地板是工程硬木地板，合同只说了hardwood 楼梯和一楼地板，我基本要求是一样的材料，没想整出两种hardwood，是不是oa

原文如下：

I hope that I am understanding your question correctly.  The floors are an engineered hardwood that is installed in planks.  The stairs are solid oak treads that are stained to compliment the floors.  This makes for a quality installation that will last for years to come.
