What Is Prefabricated Trimless Drywall?

A system revolutionizing the way drywall can be installed.

Creating efficiencies while increasing quality is a focus on every job for SDI. Prefabricated drywall is a revolutionary system that makes creating intricate shapes and assemblies from drywall less labor intensive while producing a higher quality product.

Prefabricated drywall pieces are created using a panel machine and customized for almost any project. The pieces are prefabricated off-site and then delivered to the project for installation on pre-assembled stud framing. joinUpon installation, there is minimal taping, sanding, and finishing required, and the need for costly labour intensive corner beadwork and joint work is minimized. Joints and corners are already complete with pre-fabricated sections allowing the installation process to go quicker. This significantly reduces the work that goes into creating corners and joints in tight and hard to reach spaces.

Projects that require a lot of manual cutting or that have complex curves have always been cumbersome and time consuming. Now, even the most challenging assemblies can be completed more efficiently with:

Increased overall quality: Shapes are fabricated in our facility in an open staging area that allows for quality control. Joints are finished with a reduced amount of mud creating a cleaner finish as pre-formed corners and unbroken paper faces eliminate finishing defects. This process creates a perfectly formed product set to specifications with sharp and crisp angles - eliminating the need for sanding and patching of wall angle gaps at flared corners.

Custom-designed for each project: Prefabrications are designed using specifications created at the site. Products can be fabricated in a variety of shapes and sizes including soffits, column covers, curtain pockets, and curvatures. The panels machine also allows for Intricate detailing to be applied for specialty pieces. 

Less finishing and on-site labor; Fewer materials with less waste: Using prefabricated drywall can reduce labor time by up to 70% with installation being dramatically reduced by installing finished profiles. By eliminating corner bead, there are savings on corner trim, compound, and finishing time. Shapes are fabricated in an SDI off-site location. This reduces on-site personnel congestion, waste production from drywall scrap, and taping labor. It also decreases time for installation and finishing, making the project ready for paint earlier.

With spire in place, Wilshire Grand stretches skyward to become tallest building in western U.S.


At 7:22 a.m. Saturday, crane operator Josh Wiggins received his instructions on the radio.

“All free and clear. Coming up.”

From his cab 1,000 feet above downtown Los Angeles, Wiggins pulled back the hoist level and began raising the last piece of steel at the Wilshire Grand job site.

The 58-foot, hollow cylinder, weighing 20,000 pounds, glided vertically into the space above the street, almost in levitation.Eight minutes later, Wiggins lowered his 4-foot diameter load into position, bringing it to rest atop its partner, a 236-foot cylinder that had been raised earlier, one straw on top of another. The spire for the Wilshire Grand, 1,100 feet above Figueroa Street, was complete, and Los Angeles could claim title to home of the tallest skyscraper west of the Mississippi River.

Nearly 50 construction workers in yellow-and-orange fluorescent vests congregated on the high-rise’s unfinished floors, gazing skyward. A pair of helicopters circled beneath gray skies, photographers leaning through open doors to document the occasion, and on the roof of the nearby Aon Center, 62 stories high, architects, engineers, construction managers and media crowded the parapet, cameras poised.

Positioned inside the spire and out of sight, two iron workers, Eric Madrigal and Dan Cobbs, began torque-wrenching the nearly 70 bolts that would hold the two sections together. Wiggins held the crane’s load steady.

In addition to its height, the Wilshire Grand has the added distinction of changing the skyline of Los Angeles with a rooftop that is neither truncated nor flat. The spire, designed in tandem with a 10-story steel-and-glass crown, rises above an outdoor terrace on the 73rd floor. The architectural features of the spire, which is illuminated at night, are mostly ornamental and were developed in negotiation with city officials and the Los Angeles Fire Department.

Los Angeles’ flat-topped skyline had been required since the 1970s as a safety feature to accommodate landing sites for helicopters in the event of emergencies. Architects for the Wilshire Grand, however, proposed an alternative that reflected a more modern approach to high-rise design. It included a tactical landing platform, an elevator designed exclusively for firefighting and a video surveillance system to monitor each floor in the event of a fire.

With half the bolts in place, Wiggins began to let the weight of his load settle into place. Madrigal climbed the ladder inside the spire to the top, where he stepped through a small hatch. Standing on a narrow lip just beneath the tip — 18 feet of burnished and perforated stainless steel that soon will be lit red, blue, green or gold — he unfastened the spreader to the crane. The spire was in place.

At 8:06 a.m., Wiggins delivered two blasts from the crane’s air horn, and Madrigal lifted his arms over his head.

With a red navigation beacon glowing at its peak, the Wilshire Grand had entered the history books.
