In which direction should drywall be fastened to steel studs?

Fastening drywall to steel studs in one direction only refers to the recommended practice of installing drywall sheets horizontally. This orientation provides several advantages, including enhanced structural integrity and reducing the number of joints between sheets, which can make finishing easier and improve the overall appearance of the wall.

When drywall is installed horizontally, the seams are staggered, which is less likely to produce visible lines after finishing compared to vertical installation. Additionally, horizontal installation distributes the weight more evenly across the studs, reducing the potential for sagging, particularly in wider walls. This approach also allows for easier hanging of fixtures and helps to maintain the alignment of the sheets throughout the installation process.

Installing drywall vertically is less common and often leads to more seams, which can complicate the finishing process. Although it can still be done, especially in smaller spaces or when using shorter panels, horizontal installation remains the preferred method in most commercial applications to ensure a more durable and visually appealing finish.
