The Beijing engineering community is absolutely buzzing:

At the Zhongguancun Cuihu Science and Technology Park—a key development project spanning a total construction area of 88,340.09 square meters—the Beijing Fifth Construction Engineering Group Co., Ltd. (a firm that has won the prestigious Luban Award 14 times) achieved results previously unimaginable in the industry. By utilizing Deruitu gypsum sprayers and DM plastering machines, a team of just four workers was able to consistently complete the entire wall-plastering process for 800 square meters in a single day. A surface area that would have taken traditional plasterers two months to finish was completed and delivered by Deruitu—to the highest quality standards—in just 28 days!

For many, the initial reaction is: "Impossible—that’s absolute nonsense." So, let’s strip away the hype and crunch the numbers for the entire engineering community: just how disruptive is this level of efficiency, really?

For the complete workflow of interior gypsum plastering—assuming peak performance, zero rework, and no interruptions—the absolute maximum daily output for a single worker is merely 80 to 100 square meters. Based on this upper-limit standard, a team of four skilled craftsmen, working flat out, could cover at most 400 square meters in a single day. To complete a standard surface area of 22,400 square meters, they would require 56 days—working non-stop without eating, drinking, or resting—which amounts to a full two months. However, on a real-world construction site, one must account for material handling, worker breaks, detailed touch-ups, environmental compliance stoppages, and corrective rework; consequently, the actual project duration would inevitably be longer—it is entirely possible that even three months would not be sufficient to bring the project to final completion.

However, Deruitu’s "Spray-and-Trowel" golden combination—staffed by a fixed four-person team—delivers exceptional efficiency: one person loads the DMIX plastering machine, one operates the spray gun, one runs the DM troweling machine to level and smooth the surface, and one handles the final finishing touches. This setup consistently produces 800 square meters of fully finished wall surfaces per day; for an equivalent project area, it ensures a flawless handover within just 28 days—directly cutting the construction schedule by over 50%!

Many industry insiders ask: With so many spraying and plastering machines on the market, why does Beijing No. 5 Construction specifically place its trust in Deruitu? The answer is simple: We never merely sell two standalone pieces of equipment; rather, for large-scale, benchmark projects, we provide a complete, closed-loop solution—one that covers the entire process from material application to final project acceptance, ensuring zero rework.

✅ Front-end Spraying: Stable Flow, Controlled Waste

The DMIX gypsum spraying machine delivers fully automated mixing, high-pressure pumping, and uniform spraying. This ensures deep adhesion between the gypsum mortar and the wall substrate, effectively eliminating the risks of hollowing and cracking at the very source.

✅ Back-end Finishing: Millimeter-Level Precision, 100% Standardization

The DM plastering machine is equipped with a precision leveling system that integrates plastering, flattening, and finishing into a single, seamless step. It maintains wall flatness and verticality within a tolerance of 2mm, thereby eliminating reliance on the individual craftsmanship of skilled workers. Whether the project covers 100 square meters or 100,000 square meters, it achieves millimeter-level uniformity in construction, allowing you to bid farewell to the nightmare of rework and rectification.

✅ Integrated Closed Loop: Zero Process Disconnects, Zero Internal Inefficiencies

The spraying and finishing stages are seamlessly interconnected: as the front-end spraying applies material to the wall, the back-end finishing follows up in perfect synchronization. With no waiting intervals and no procedural gaps, a four-person team can execute the entire workflow as a continuous assembly line. This eliminates the need for additional manpower or repetitive cross-construction tasks, drastically reducing on-site management complexity and significantly lowering safety risks—making it the perfect solution for the continuous construction demands of large-scale projects.

Delivery marks not the end, but the beginning; service is our true core competence.

Many engineering professionals have fallen into this common trap: equipment is purchased and delivered, only for the manufacturer to vanish completely. When issues arise on-site, there is no one to turn to; commissioning and training are left entirely to trial and error, and perfectly good equipment ends up becoming nothing more than a useless fixture on the construction site.

The reason Deruitu has been able to forge long-term strategic partnerships with over 50 central and state-owned construction groups across the country is never due to one-off transactions, but rather through comprehensive, end-to-end engineering services that provide personalized support across every stage and scenario of a project.

For this benchmark project in Zhongguancun, we established a dedicated technical service team. During the initial engagement phase, we developed a comprehensive, tailored implementation plan—covering equipment selection, crew allocation, and construction workflows—based on the project's specific construction milestones, site conditions, and acceptance criteria.

 On the day the equipment arrived on-site, our technical team remained present throughout the entire process to oversee installation and commissioning, as well as to provide one-on-one operational training, thereby ensuring that the crew could immediately begin stable operations that very day. Throughout the entire construction period, we maintained a 24-hour emergency response capability, with technical engineers continuously monitoring the site to promptly resolve any unforeseen issues; this ensured uninterrupted equipment operation and prevented any delays in the project schedule, truly realizing our commitment to "ready-to-use upon delivery, effective immediately upon use."

From urban landmarks to public welfare projects, from industrial parks to national-level hubs of scientific and technological innovation, Deruitu has always firmly believed that intelligent construction is never merely a lofty, abstract concept; rather, it is a tangible, practical solution that genuinely empowers engineering professionals to boost efficiency, reduce costs, ensure quality, and avoid pitfalls.
